Pin J1_6 is used as a CLKOUT signal. Connect this pin to an Oscilloscope for viewing the signal.
Prepare the Demo
Connect a USB cable between the host PC and the FRDM board J10.
Open a serial terminal with the following settings:
115200 baud rate
8 data bits
No parity
One stop bit
No flow control
Download the program to the target board.
Either press the reset button on your board or launch the debugger in your IDE to begin running the demo.
Running the demo
The demo sets the MicroTick Timer as a wake up source and puts the device in sleep mode. The MicroTick timer wakes up the device.
After wake up：
(1)The blue LED on the board blinking. (2)CLKOUT signal changing can be seen on pin J1_6. And the frequency of output signal will double.
If the demo run successfully, you will see the log from debug console:
Utick wakeup demo start...
Wakeup from sleep mode...
