Comments

This function only returns valid results if the hal_save_non_volatile_data API was called from the user's Non-Maskable Interrupt (NMI) callback or at program exit and the init/restore hal_init_non_volatile_data function was called following the reboot.

This function may also be used from within an NMI callback to access the cause of the current shut down interrupt.   In this case the reading will be either REBOOT_WATCHDOG or REBOOT_POWER_FAIL .
