Application enters stop mode.
V
CPU in stop mode.
V
Power-fail not detected because power-fail monitor
is disabled.
V
An interrupt occurs that causes the CPU to exit
stop mode.
Power-fail monitor is turned on, detects a power-fail
warning, and sets the power-fail interrupt flag.
Turn on regulator and crystal.

On stop mode exit, CPU vectors to the higher
priority of power-fail and the interrupt that causes
stop mode exit.
