The MCU exits stop mode by a reset or peripheral function interrupt.
Figure 10.15 shows the Time from Stop Mode to Interrupt Routine Execution.
When using a peripheral function interrupt to exit stop mode, set up the following before setting the CM10 bit
to 1.
If the clock used immediately before stop mode is a system clock and stop mode is exited by a peripheral
function interrupt, the CPU clock becomes the previous system clock divided by 8.

(1) Set the interrupt priority level in bits ILVL2 to ILVL0 of the peripheral function interrupts to be used for
(2) Set the I flag to 1.
(3) Operates the peripheral function to be used for exiting stop mode.

for exiting stop mode to 000b (interrupt disabled).
When exiting by a peripheral function interrupt, the interrupt sequence is executed when an interrupt
request is generated and the CPU clock supply is started.
