Stop mode is exited by the hardware reset, NMI interrupt, or peripheral function interrupts (key input
interrupt and INT interrupt).
When the hardware reset or NMI interrupt, but not the peripheral function interrupts, is used to exit wait
mode, set all ILVL2 to ILVL0 bits in the interrupt control registers for the peripheral function interrupt to
"000
