note:if need use secure pint,you just needs to modify base address. Find PINT baseaddr in source file, you need change it to SECPINT. everything else stays the same.Because of SECURE PINT device only support PORT0,so we only need to config secure pint interrupt 0. For example, the following PINT_Init(PINT); PINT_PinInterruptConfig(PINT, kPINT_PinInt0, kPINT_PinIntEnableRiseEdge); PINT_SetCallback(PINT, pint_intr_callback); PINT_EnableCallback(PINT, kPINT_PinInt0); Change the above three lines into the following: PINT_Init(SECPINT); PINT_PinInterruptConfig(SECPINT, kPINT_SecPinInt0, kPINT_PinIntEnableRiseEdge); PINT_SetCallback(SECPINT, pint_intr_callback); PINT_EnableCallbackByIndex(SECPINT, kPINT_SecPinInt0);
After configuring secure pint device, you can see log output "The interrupt callback prints "PINT Pin Interrupt 0 event detected"
by press SW2 button.

Running the demo
This demo is an external flash plain load demo, ROM will copy image in external flash to SRAMX to run:
Build the demo to generate a bin file. Note: If need to generate bin file using MCUXpresso IDE, below steps need to be followed: Set in example Properties->C/C++ Build->Settings->Build steps->Post-build steps->Edit enbable arm-none-eabi-objcopy -v -O binary “&{BuildArtifactFileName}” “&{BuildArtifactFileBaseName}.bin”
This plainload example linked the vector table to 0x00000000, but program to external flash 0x10000000.
Program the bin file to external on board flash via SEGGER J-FLASH Lite(V6.22 or higher):
a. Open SEGGER J-FLASH Lite, select device LPC54S018.
b. Click the ‘Erase Chip’ to erase the extrenal flash.(if can not success, press SW4 button and reset the board, and try to erase again)
c. Select the bin data file, set the ‘.bin/Erase Start’ address to 0x10000000, then click ‘Program Device’ Note: Please use above way to program the binary file built by armgcc tool chain to external flash. For IAR, KEIL, MCUXpresso IDE, you can use the IDE tool to program the external flash.

This example configures “Pin Interrupt 0” to be invoked when SW4 switch is pressed by the user. The interrupt callback prints “PINT Pin Interrupt 0 event detected”. “Pin Interrupt 1” is is configured to be invoked when SW2 is pressed. The interrupt callback prints “PINT Pin Interrupt 1 event detected”. “Pin Interrupt 2” is configured to be invoked when SW3 is pressed. The interrupt callback prints “PINT Pin Interrupt 2 event detected”.
note:if need use secure pint,you just needs to modify base address. Find PINT baseaddr in source file, you need change it to SECPINT. everything else stays the same.Because of SECURE PINT device only support PORT0,so we only need to config secure pint interrupt 0. For example, the following PINT_Init(PINT); PINT_PinInterruptConfig(PINT, kPINT_PinInt0, kPINT_PinIntEnableRiseEdge); PINT_SetCallback(PINT, pint_intr_callback);
PINT_EnableCallbackByIndex(PINT, kPINT_PinInt0);
Change the above three lines into the following:
PINT_Init(SECPINT);
PINT_PinInterruptConfig(SECPINT, kPINT_SecPinInt0, kPINT_PinIntEnableRiseEdge);
PINT_SetCallback(SECPINT, pint_intr_callback);
PINT_EnableCallbackByIndex(SECPINT, kPINT_SecPinInt0);
After configuring secure pint device, you can see log output "The interrupt callback prints "PINT Pin Interrupt 0 event detected"
by press SW4 button.
