void FLEXIO_SPI_MasterInit(FLEXIO_SPI_Type *base, flexio_spi_master_config_t *masterConfig, uint32_t srcClock_Hz)#

Ungates the FlexIO clock, resets the FlexIO module, configures the FlexIO SPI master hardware, and configures the FlexIO SPI with FlexIO SPI master configuration. The configuration structure can be filled by the user, or be set with default values by the FLEXIO_SPI_MasterGetDefaultConfig().

Example

FLEXIO_SPI_Type spiDev = {
.flexioBase = FLEXIO,
.SDOPinIndex = 0,
.SDIPinIndex = 1,
.SCKPinIndex = 2,
.CSnPinIndex = 3,
.shifterIndex = {0,1},
.timerIndex = {0,1}
};
flexio_spi_master_config_t config = {
.enableMaster = true,
.enableInDoze = false,
.enableInDebug = true,
.enableFastAccess = false,
.baudRate_Bps = 500000,
.phase = kFLEXIO_SPI_ClockPhaseFirstEdge,
.direction = kFLEXIO_SPI_MsbFirst,
.dataMode = kFLEXIO_SPI_8BitMode
};
FLEXIO_SPI_MasterInit(&spiDev, &config, srcClock_Hz);

Note

1.FlexIO SPI master only support CPOL = 0, which means clock inactive low. 2.For FlexIO SPI master, the input valid time is 1.5 clock cycles, for slave the output valid time is 2.5 clock cycles. So if FlexIO SPI master communicates with other spi IPs, the maximum baud rate is FlexIO clock frequency divided by 2*2=4.

Note

1.Only one timer is needed in the FlexIO SPI slave. As a result, the second timer index is ignored. 2.FlexIO SPI slave only support CPOL = 0, which means clock inactive low. 3.For FlexIO SPI master, the input valid time is 1.5 clock cycles, for slave the output valid time is 2.5 clock cycles.

This function initializes the FlexIO UART handle, which can be used for other FlexIO UART transactional APIs. Call this API once to get the initialized handle.

The UART driver supports the “background” receiving, which means that users can set up a RX ring buffer optionally. Data received is stored into the ring buffer even when the user doesn’t call the FLEXIO_UART_TransferReceiveNonBlocking() API. If there is already data received in the ring buffer, users can get the received data from the ring buffer directly. The ring buffer is disabled if passing NULL as ringBuffer.

Parameters:

base – to FLEXIO_UART_Type structure.
handle – Pointer to the flexio_uart_handle_t structure to store the transfer state.
callback – The callback function.
userData – The parameter of the callback function.

Return values:

kStatus_Success – Successfully create the handle.
kStatus_OutOfRange – The FlexIO type/handle/ISR table out of range.

void FLEXIO_UART_TransferStartRingBuffer(FLEXIO_UART_Type *base, flexio_uart_handle_t *handle, uint8_t *ringBuffer, size_t ringBufferSize)#

Sets up the RX ring buffer.

This function sets up the RX ring buffer to a specific UART handle.

When the RX ring buffer is used, data received is stored into the ring buffer even when the user doesn’t call the UART_ReceiveNonBlocking() API. If there is already data received in the ring buffer, users can get the received data from the ring buffer directly.

Note

When using the RX ring buffer, one byte is reserved for internal use. In other words, if ringBufferSize is 32, only 31 bytes are used for saving data.

Parameters:

base – Pointer to the FLEXIO_UART_Type structure.
handle – Pointer to the flexio_uart_handle_t structure to store the transfer state.
ringBuffer – Start address of ring buffer for background receiving. Pass NULL to disable the ring buffer.
ringBufferSize – Size of the ring buffer.

void FLEXIO_UART_TransferStopRingBuffer(FLEXIO_UART_Type *base, flexio_uart_handle_t *handle)#

Aborts the background transfer and uninstalls the ring buffer.

This function aborts the background transfer and uninstalls the ring buffer.

Parameters:

base – Pointer to the FLEXIO_UART_Type structure.
handle – Pointer to the flexio_uart_handle_t structure to store the transfer state.

status_t FLEXIO_UART_TransferSendNonBlocking(FLEXIO_UART_Type *base, flexio_uart_handle_t *handle, flexio_uart_transfer_t *xfer)#

Transmits a buffer of data using the interrupt method.

This function sends data using an interrupt method. This is a non-blocking function, which returns directly without waiting for all data to be written to the TX register. When all data is written to the TX register in ISR, the FlexIO UART driver calls the callback function and passes the kStatus_FLEXIO_UART_TxIdle as status parameter.

Note

The kStatus_FLEXIO_UART_TxIdle is passed to the upper layer when all data is written to the TX register. However, it does not ensure that all data is sent out.

Parameters:

base – Pointer to the FLEXIO_UART_Type structure.
handle – Pointer to the flexio_uart_handle_t structure to store the transfer state.
xfer – FlexIO UART transfer structure. See flexio_uart_transfer_t.

Return values:

kStatus_Success – Successfully starts the data transmission.
kStatus_UART_TxBusy – Previous transmission still not finished, data not written to the TX register.

void FLEXIO_UART_TransferAbortSend(FLEXIO_UART_Type *base, flexio_uart_handle_t *handle)#

Aborts the interrupt-driven data transmit.

This function aborts the interrupt-driven data sending. Get the remainBytes to find out how many bytes are still not sent out.

Parameters:

base – Pointer to the FLEXIO_UART_Type structure.
handle – Pointer to the flexio_uart_handle_t structure to store the transfer state.

status_t FLEXIO_UART_TransferGetSendCount(FLEXIO_UART_Type *base, flexio_uart_handle_t *handle, size_t *count)#

Gets the number of bytes sent.

This function gets the number of bytes sent driven by interrupt.

Parameters:

base – Pointer to the FLEXIO_UART_Type structure.
handle – Pointer to the flexio_uart_handle_t structure to store the transfer state.
count – Number of bytes sent so far by the non-blocking transaction.

Return values:

kStatus_NoTransferInProgress – transfer has finished or no transfer in progress.
kStatus_Success – Successfully return the count.

status_t FLEXIO_UART_TransferReceiveNonBlocking(FLEXIO_UART_Type *base, flexio_uart_handle_t *handle, flexio_uart_transfer_t *xfer, size_t *receivedBytes)#

Receives a buffer of data using the interrupt method.

This function receives data using the interrupt method. This is a non-blocking function, which returns without waiting for all data to be received. If the RX ring buffer is used and not empty, the data in ring buffer is copied and the parameter receivedBytes shows how many bytes are copied from the ring buffer. After copying, if the data in ring buffer is not enough to read, the receive request is saved by the UART driver. When new data arrives, the receive request is serviced first. When all data is received, the UART driver notifies the upper layer through a callback function and passes the status parameter kStatus_UART_RxIdle. For example, if the upper layer needs 10 bytes but there are only 5 bytes in the ring buffer, the 5 bytes are copied to xfer->data. This function returns with the parameter receivedBytes set to 5. For the last 5 bytes, newly arrived data is saved from the xfer->data[5]. When 5 bytes are received, the UART driver notifies upper layer. If the RX ring buffer is not enabled, this function enables the RX and RX interrupt to receive data to xfer->data. When all data is received, the upper layer is notified.

Parameters:

base – Pointer to the FLEXIO_UART_Type structure.
handle – Pointer to the flexio_uart_handle_t structure to store the transfer state.
xfer – UART transfer structure. See flexio_uart_transfer_t.
receivedBytes – Bytes received from the ring buffer directly.

Return values:

kStatus_Success – Successfully queue the transfer into the transmit queue.
kStatus_FLEXIO_UART_RxBusy – Previous receive request is not finished.

Create a new handle for the I3C master DMA APIs. 
The creation of a handle is for use with the DMA APIs. Once a handle is created, there is not a corresponding destroy handle. If the user wants to terminate a transfer, the I3C_MasterTransferAbortDMA() API shall be called.
For devices where the I3C send and receive DMA requests are OR’d together, the txDmaHandle parameter is ignored and may be set to NULL.

Parameters:

base – The I3C peripheral base address. 
handle – Pointer to the I3C master driver handle. 
callback – User provided pointer to the asynchronous callback function. 
userData – User provided pointer to the application callback data. 
rxDmaHandle – Handle for the DMA receive channel. Created by the user prior to calling this function. 
txDmaHandle – Handle for the DMA transmit channel. Created by the user prior to calling this function. 







status_t I3C_MasterTransferEDMA(I3C_Type *base, i3c_master_edma_handle_t *handle, i3c_master_transfer_t *transfer)#

Performs a non-blocking DMA-based transaction on the I3C bus. 
The callback specified when the handle was created is invoked when the transaction has completed.

Note
On parts affected by ERR053412, the I3C controller stalls SCL when the RxFIFO becomes full and does not recover after CPU read FIFO, bus will be stalling indefinitely. This DMA-based API services the RxFIFO with EDMA so it never fills, and is the recommended workaround on affected parts.


Parameters:

base – The I3C peripheral base address. 
handle – Pointer to the I3C master driver handle. 
transfer – The pointer to the transfer descriptor. 


Return values:

kStatus_Success – The transaction was started successfully. 
kStatus_I3C_Busy – Either another master is currently utilizing the bus, or another DMA transaction is already in progress. 







status_t I3C_MasterTransferGetCountEDMA(I3C_Type *base, i3c_master_edma_handle_t *handle, size_t *count)#

Returns number of bytes transferred so far. 

Parameters:

base – The I3C peripheral base address. 
handle – Pointer to the I3C master driver handle. 
count – [out] Number of bytes transferred so far by the non-blocking transaction. 


Return values:

kStatus_Success – 
kStatus_NoTransferInProgress – There is not a DMA transaction currently in progress. 







void I3C_MasterTransferAbortEDMA(I3C_Type *base, i3c_master_edma_handle_t *handle)#

Terminates a non-blocking I3C master transmission early. 

Note

Parameters:

base – The I3C peripheral base address. 
handle – Pointer to the I3C master driver handle. 







void I3C_MasterTransferEDMAHandleIRQ(I3C_Type *base, void *i3cHandle)#

Reusable routine to handle master interrupts.

void I3C_SlaveTransferCreateHandle(I3C_Type *base, i3c_slave_handle_t *handle, i3c_slave_transfer_callback_t callback, void *userData)#

Creates a new handle for the I3C slave non-blocking APIs. 
The creation of a handle is for use with the non-blocking APIs. Once a handle is created, there is not a corresponding destroy handle. If the user wants to terminate a transfer, the I3C_SlaveTransferAbort() API shall be called.

Note
The function also enables the NVIC IRQ for the input I3C. Need to notice that on some SoCs the I3C IRQ is connected to INTMUX, in this case user needs to enable the associated INTMUX IRQ in application.


Parameters:

base – The I3C peripheral base address. 
handle – [out] Pointer to the I3C slave driver handle. 
callback – User provided pointer to the asynchronous callback function. 
userData – User provided pointer to the application callback data. 







status_t I3C_SlaveTransferNonBlocking(I3C_Type *base, i3c_slave_handle_t *handle, uint32_t eventMask)#

Starts accepting slave transfers. 
Call this API after calling I2C_SlaveInit() and I3C_SlaveTransferCreateHandle() to start processing transactions driven by an I2C master. The slave monitors the I2C bus and pass events to the callback that was passed into the call to I3C_SlaveTransferCreateHandle(). The callback is always invoked from the interrupt context.
The set of events received by the callback is customizable. To do so, set the eventMask parameter to the OR’d combination of i3c_slave_transfer_event_t enumerators for the events you wish to receive. The kI3C_SlaveTransmitEvent and kI3C_SlaveReceiveEvent events are always enabled and do not need to be included in the mask. Alternatively, you can pass 0 to get a default set of only the transmit and receive events that are always enabled. In addition, the kI3C_SlaveAllEvents constant is provided as a convenient way to enable all events.

Parameters:

base – The I3C peripheral base address. 
handle – Pointer to struct: _i3c_slave_handle structure which stores the transfer state. 
eventMask – Bit mask formed by OR’ing together i3c_slave_transfer_event_t enumerators to specify which events to send to the callback. Other accepted values are 0 to get a default set of only the transmit and receive events, and kI3C_SlaveAllEvents to enable all events.


Return values:

kStatus_Success – Slave transfers were successfully started. 
kStatus_I3C_Busy – Slave transfers have already been started on this handle. 







status_t I3C_SlaveTransferGetCount(I3C_Type *base, i3c_slave_handle_t *handle, size_t *count)#

Gets the slave transfer status during a non-blocking transfer. 

Parameters:

base – The I3C peripheral base address.

Call this API after calling I2C_SlaveInit() and LPI2C_SlaveTransferCreateHandle() to start processing transactions driven by an I2C master. The slave monitors the I2C bus and pass events to the callback that was passed into the call to LPI2C_SlaveTransferCreateHandle(). The callback is always invoked from the interrupt context.
The set of events received by the callback is customizable. To do so, set the eventMask parameter to the OR’d combination of lpi2c_slave_transfer_event_t enumerators for the events you wish to receive. The kLPI2C_SlaveTransmitEvent and kLPI2C_SlaveReceiveEvent events are always enabled and do not need to be included in the mask. Alternatively, you can pass 0 to get a default set of only the transmit and receive events that are always enabled. In addition, the kLPI2C_SlaveAllEvents constant is provided as a convenient way to enable all events.

Parameters:

base – The LPI2C peripheral base address. 
handle – Pointer to lpi2c_slave_handle_t structure which stores the transfer state. 
eventMask – Bit mask formed by OR’ing together lpi2c_slave_transfer_event_t enumerators to specify which events to send to the callback. Other accepted values are 0 to get a default set of only the transmit and receive events, and kLPI2C_SlaveAllEvents to enable all events.


Return values:

kStatus_Success – Slave transfers were successfully started. 
kStatus_LPI2C_Busy – Slave transfers have already been started on this handle.

static inline void LPSPI_SetMasterSlaveMode(LPSPI_Type *base, lpspi_master_slave_mode_t mode)#

Configures the LPSPI for either master or slave. 
Note that the CFGR1 should only be written when the LPSPI is disabled (LPSPIx_CR_MEN = 0).

Parameters:

base – LPSPI peripheral address. 
mode – Mode setting (master or slave) of type lpspi_master_slave_mode_t. 







static inline void LPSPI_SelectTransferPCS(LPSPI_Type *base, lpspi_which_pcs_t select)#

Configures the peripheral chip select used for the transfer. 

Parameters:

base – LPSPI peripheral address. 
select – LPSPI Peripheral Chip Select (PCS) configuration. 







static inline void LPSPI_SetPCSContinous(LPSPI_Type *base, bool IsContinous)#

Set the PCS signal to continuous or uncontinuous mode. 

Note
In master mode, continuous transfer will keep the PCS asserted at the end of the frame size, until a command word is received that starts a new frame. So PCS must be set back to uncontinuous when transfer finishes. In slave mode, when continuous transfer is enabled, the LPSPI will only transmit the first frame size bits, after that the LPSPI will transmit received data back (assuming a 32-bit shift register).


Parameters:

base – LPSPI peripheral address. 
IsContinous – True to set the transfer PCS to continuous mode, false to set to uncontinuous mode. 







static inline bool LPSPI_IsMaster(LPSPI_Type *base)#

Parameters:

base – LPSPI peripheral address. 


Returns:
Returns true if the module is in master mode or false if the module is in slave mode.

static inline void LPSPI_SetFifoWatermarks(LPSPI_Type *base, uint32_t txWater, uint32_t rxWater)#

Sets the transmit and receive FIFO watermark values. 
This function allows the user to set the receive and transmit FIFO watermarks. The function does not compare the watermark settings to the FIFO size. The FIFO watermark should not be equal to or greater than the FIFO size. It is up to the higher level driver to make this check.

Parameters:

base – LPSPI peripheral address. 
txWater – The TX FIFO watermark value. Writing a value equal or greater than the FIFO size is truncated. 
rxWater – The RX FIFO watermark value. Writing a value equal or greater than the FIFO size is truncated. 







static inline void LPSPI_SetAllPcsPolarity(LPSPI_Type *base, uint32_t mask)#

Configures all LPSPI peripheral chip select polarities simultaneously. 
Note that the CFGR1 should only be written when the LPSPI is disabled (LPSPIx_CR_MEN = 0).
This is an example: PCS0 and PCS1 set to active low and other PCSs set to active high. Note that the number of PCS is device-specific. 
LPSPI_SetAllPcsPolarity(base, kLPSPI_Pcs0ActiveLow | kLPSPI_Pcs1ActiveLow);




Parameters:

base – LPSPI peripheral address. 
mask – The PCS polarity mask; Use the enum _lpspi_pcs_polarity. 







static inline void LPSPI_SetFrameSize(LPSPI_Type *base, uint32_t frameSize)#

Configures the frame size. 
The minimum frame size is 8-bits and the maximum frame size is 4096-bits. If the frame size is less than or equal to 32-bits, the word size and frame size are identical. If the frame size is greater than 32-bits, the word size is 32-bits for each word except the last (the last word contains the remainder bits if the frame size is not divisible by 32). The minimum word size is 2-bits. A frame size of 33-bits (or similar) is not supported.
Note 1: The transmit command register should be initialized before enabling the LPSPI in slave mode, although the command register does not update until after the LPSPI is enabled. After it is enabled, the transmit command register should only be changed if the LPSPI is idle.
Note 2: The transmit and command FIFO is a combined FIFO that includes both transmit data and command words. That means the TCR register should be written to when the Tx FIFO is not full.

Parameters:

base – LPSPI peripheral address. 
frameSize – The frame size in number of bits. 







uint32_t LPSPI_MasterSetBaudRate(LPSPI_Type *base, uint32_t baudRate_Bps, uint32_t srcClock_Hz, uint32_t *tcrPrescaleValue)#

Sets the LPSPI baud rate in bits per second. 
This function takes in the desired bitsPerSec (baud rate) and calculates the nearest possible baud rate without exceeding the desired baud rate and returns the calculated baud rate in bits-per-second. It requires the caller to provide the frequency of the module source clock (in Hertz). Note that the baud rate does not go into effect until the Transmit Control Register (TCR) is programmed with the prescale value. Hence, this function returns the prescale tcrPrescaleValue parameter for later programming in the TCR. The higher level peripheral driver should alert the user of an out of range baud rate input.
Note that the LPSPI module must first be disabled before configuring this. Note that the LPSPI module must be configured for master mode before configuring this.

Parameters:

base – LPSPI peripheral address. 
baudRate_Bps – The desired baud rate in bits per second. 
srcClock_Hz – Module source input clock in Hertz. 
tcrPrescaleValue – The TCR prescale value needed to program the TCR. 


Returns:
The actual calculated baud rate. This function may also return a “0” if the LPSPI is not configured for master mode or if the LPSPI module is not disabled. 






void LPSPI_MasterSetDelayScaler(LPSPI_Type *base, uint32_t scaler, lpspi_delay_type_t whichDelay)#

This function configures the following: SCK to PCS delay, or PCS to SCK delay, or The configurations must occur between the transfer delay.
The delay names are available in type lpspi_delay_type_t.
The user passes the desired delay along with the delay value. This allows the user to directly set the delay values if they have pre-calculated them or if they simply wish to manually increment the value.
Note that the LPSPI module must first be disabled before configuring this. Note that the LPSPI module must be configured for master mode before configuring this.

Parameters:

base – LPSPI peripheral address. 
scaler – The 8-bit delay value 0x00 to 0xFF (255). 
whichDelay – The desired delay to configure, must be of type lpspi_delay_type_t. 







uint32_t LPSPI_MasterSetDelayTimes(LPSPI_Type *base, uint32_t delayTimeInNanoSec, lpspi_delay_type_t whichDelay, uint32_t srcClock_Hz)#

This function configures the SCK to PCS delay, PCS to SCK delay, or the delay between transfers. The delay names are available in type lpspi_delay_type_t.
The function calculates the value needed for the desired delay parameter and returns the actual calculated delay. An exact delay match may not be possible, in which case the closest match is calculated without going below the desired delay value. If the input exceeds the maximum capability, the maximum supported delay is returned.
Note that the LPSPI module must first be disabled before configuring this. Note that the LPSPI module must be configured for master mode before configuring this.

Parameters:

base – LPSPI peripheral address. 
delayTimeInNanoSec – The desired delay value in nanoseconds. 
whichDelay – The desired delay to configure, must be of type lpspi_delay_type_t.

LPTMR runs on a low-power clock that is asynchronous to the EDMA bus clock. On some EDMA IP variants the channel has TWO gates that must BOTH be opened for an LPTMR request to be accepted: the base hardware request gate (ERQ, opened by EDMA_EnableChannelRequest()) and an extra asynchronous-request gate (opened by EDMA_EnableAsyncRequest() on EDMA4; the classic EDMA + DMAMUX combination does not need this).


Parameters:

base – base LPTMR peripheral base address 
enable – Switcher of timer DMA feature. “true” means to enable, “false” means to disable. 







struct _lptmr_config#


#include <fsl_lptmr.h>
LPTMR config structure. 
This structure holds the configuration settings for the LPTMR peripheral. To initialize this structure to reasonable defaults, call the LPTMR_GetDefaultConfig() function and pass a pointer to your configuration structure instance.
The configuration struct can be made constant so it resides in flash.

void LPUART_TransferCreateHandle(LPUART_Type *base, lpuart_handle_t *handle, lpuart_transfer_callback_t callback, void *userData)#

Initializes the LPUART handle. 
This function initializes the LPUART handle, which can be used for other LPUART transactional APIs. Usually, for a specified LPUART instance, call this API once to get the initialized handle.
The LPUART driver supports the “background” receiving, which means that user can set up an RX ring buffer optionally. Data received is stored into the ring buffer even when the user doesn’t call the LPUART_TransferReceiveNonBlocking() API. If there is already data received in the ring buffer, the user can get the received data from the ring buffer directly. The ring buffer is disabled if passing NULL as ringBuffer.

Parameters:

base – LPUART peripheral base address. 
handle – LPUART handle pointer. 
callback – Callback function. 
userData – User data. 







status_t LPUART_TransferSendNonBlocking(LPUART_Type *base, lpuart_handle_t *handle, lpuart_transfer_t *xfer)#

Transmits a buffer of data using the interrupt method. 
This function send data using an interrupt method. This is a non-blocking function, which returns directly without waiting for all data written to the transmitter register. When all data is written to the TX register in the ISR, the LPUART driver calls the callback function and passes the kStatus_LPUART_TxIdle as status parameter.

Note
The kStatus_LPUART_TxIdle is passed to the upper layer when all data are written to the TX register. However, there is no check to ensure that all the data sent out. Before disabling the TX, check the kLPUART_TransmissionCompleteFlag to ensure that the transmit is finished.


Parameters:

base – LPUART peripheral base address. 
handle – LPUART handle pointer. 
xfer – LPUART transfer structure, see lpuart_transfer_t. 


Return values:

kStatus_Success – Successfully start the data transmission. 
kStatus_LPUART_TxBusy – Previous transmission still not finished, data not all written to the TX register. 
kStatus_InvalidArgument – Invalid argument. 







void LPUART_TransferStartRingBuffer(LPUART_Type *base, lpuart_handle_t *handle, uint8_t *ringBuffer, size_t ringBufferSize)#

Sets up the RX ring buffer. 
This function sets up the RX ring buffer to a specific UART handle.
When the RX ring buffer is used, data received is stored into the ring buffer even when the user doesn’t call the UART_TransferReceiveNonBlocking() API. If there is already data received in the ring buffer, the user can get the received data from the ring buffer directly.

Note
When using RX ring buffer, one byte is reserved for internal use. In other words, if ringBufferSize is 32, then only 31 bytes are used for saving data.


Parameters:

base – LPUART peripheral base address. 
handle – LPUART handle pointer. 
ringBuffer – Start address of ring buffer for background receiving. Pass NULL to disable the ring buffer. 
ringBufferSize – size of the ring buffer.

status_t LPUART_TransferReceiveNonBlocking(LPUART_Type *base, lpuart_handle_t *handle, lpuart_transfer_t *xfer, size_t *receivedBytes)#

Receives a buffer of data using the interrupt method. 
This function receives data using an interrupt method. This is a non-blocking function which returns without waiting to ensure that all data are received. If the RX ring buffer is used and not empty, the data in the ring buffer is copied and the parameter receivedBytes shows how many bytes are copied from the ring buffer. After copying, if the data in the ring buffer is not enough for read, the receive request is saved by the LPUART driver. When the new data arrives, the receive request is serviced first. When all data is received, the LPUART driver notifies the upper layer through a callback function and passes a status parameter kStatus_UART_RxIdle. For example, the upper layer needs 10 bytes but there are only 5 bytes in ring buffer. The 5 bytes are copied to xfer->data, which returns with the parameter receivedBytes set to 5. For the remaining 5 bytes, the newly arrived data is saved from xfer->data[5]. When 5 bytes are received, the LPUART driver notifies the upper layer. If the RX ring buffer is not enabled, this function enables the RX and RX interrupt to receive data to xfer->data. When all data is received, the upper layer is notified.

Parameters:

base – LPUART peripheral base address. 
handle – LPUART handle pointer. 
xfer – LPUART transfer structure, see uart_transfer_t. 
receivedBytes – Bytes received from the ring buffer directly. 


Return values:

status_t MU_ReceiveMsgTimeout(MU_Type *base, uint32_t regIndex, uint32_t *readValue)#

Blocks to receive a message with timeout protection. 
This function waits until the RX register is full and receives the message. If MU1_BUSY_POLL_COUNT is defined and non-zero, the function will timeout after the specified number of polling iterations and return kStatus_Timeout.
This function provides the same blocking behavior as MU_ReceiveMsg() but with additional timeout protection to prevent system hangs if the other core becomes unresponsive or if hardware issues occur.

Note
Both MU_ReceiveMsg() and MU_ReceiveMsgTimeout() are blocking functions. The difference is that this function includes timeout protection while MU_ReceiveMsg() waits indefinitely.


Parameters:

base – MU peripheral base address. 
regIndex – RX register index, see mu_msg_reg_index_t. 
readValue – Pointer to store the received message.

Note
Both MU_ReceiveMsg() and MU_ReceiveMsgTimeout() are blocking functions. The difference is that MU_ReceiveMsgTimeout() includes timeout protection while this function waits indefinitely.


Warning
This function does not include timeout protection and may cause system hangs if the other core becomes unresponsive. For applications requiring timeout protection, use MU_ReceiveMsgTimeout() instead.


Parameters:

base – MU peripheral base address. 
regIndex – RX register index, see mu_msg_reg_index_t.
