Application: This example code is implement NUC240 using GPIO to wake up the MCU and enter the Power Down Wakeup interrupt.
BSP Version: NUC230/240 Series BSP CMSIS V3.01.001
Hardware: NuTiny-EVB-NUC240 V1.2

When NUC240 enters Power Down mode the chip can be woken up by changing of the GPIO status. After waking up NUC240 first enters the PDWU interrupt and then enters the GPIO interrupt subroutine. Since the source of the Power Down wakeup with the priority. If the interrupt source priority is same level, the peripheral hardware interrupt will be executed first. If you want the Power Down wakeup interrupt to be response first, you can change the Power Down wakeup interrupt priority to higher level.
