Note
As soon as the STOP 0000B instruction is executed, the pins of these peripherals are set in the input
port mode, even when the control signal functions of the pins are used.
Cautions 1.
Be sure to execute the NOP instruction immediately before the STOP and HALT
instructions.
If both the interrupt request flag and interrupt enable flag corresponding to an interrupt
are set, and if the interrupt is specified to release the standby mode, the standby mode
is not set even if the STOP or HALT instruction is executed.
