&par Example Description

This example demonstrates how to use the Low-Power Timer (LPTMR) for timeout-based 
wake-up. The program initializes the LPTMR, setting a suitable prescaler and timeout 
value so that the system can automatically wake up from low power mode via an LPTMR 
interrupt. In the code, the system first prints a message and then calls __WFI() 
to enter low power mode. Once the LPTMR times out, it triggers an interrupt that 
wakes the system, after which the program prints a follow-up message to confirm 
the wake-up process.

Note: After downloading the program, please power cycle the system before testing
this example to ensure correct behavior.
