Hi,

I am looking for steps involoved in graceful shutdown of microcontroller when any of the gpio pin is used as key_switch to shutdown microcontroller.

If anyone has idea on sequence of shutting down microcontroller safely, please share your views.

Thanks

You may perform software reset

SIU.SRCR.R = 0x80000000;

in the interrupt routine on external IRQ signal connected to the button

Basically you only need to slightly modify example below:

Example MPC5777C-SIUL_External_IRQ GHS714
