set are held. The I/O port output latches and output buffer statuses are also held.
In either of these two modes, all the contents of registers, flags and data memory just before the standby mode is
Cautions 1. STOP mode can be used only when CPU is operating on the high-speed system clock or
STOP instruction execution sets the STOP mode. In the STOP mode, the high-speed system clock oscillator
stops, stopping the whole system, thereby considerably reducing the CPU operating current.
Because this mode can be released by an interrupt request, it enables intermittent operations to be carried out.
However, because a wait time is required to secure the oscillation stabilization time after the STOP mode is
released, select the HALT mode if it is necessary to start processing immediately upon interrupt request
generation.
2. When shifting to the STOP mode, be sure to stop the peripheral hardware operation before
3. The following sequence is recommended for operating current reduction of the A/D converter
4. If the internal oscillator is operating before the STOP mode is set, oscillation of the internal

executing STOP instruction.
when the standby function is used: First clear bit 7 (ADCS) of the A/D converter mode
register (ADM) to 0 to stop the A/D conversion operation, and then execute the HALT or STOP
instruction.
oscillation clock cannot be stopped in the STOP mode.
