The STOP instruction:
After exiting stop mode, the CPU clock begins running after the oscillator
stabilization delay.
If the break module is enabled, a break interrupt causes the CPU to
execute the software interrupt instruction (SWI) at the completion of the
current CPU instruction. (See
program counter vectors to $FFFC–$FFFD ($FEFC–$FEFD in monitor
mode).
A return-from-interrupt instruction (RTI) in the break routine ends the
break interrupt and returns the MCU to normal operation if the break
interrupt has been deasserted.

Clears the interrupt mask (I bit) in the condition code register,
enabling external interrupts. After exit from stop mode by external
interrupt, the I bit remains clear. After exit by reset, the I bit is set.
Disables the CPU clock.
