Stop Mode
Because this mode causes oscillation to stop and inactivates all functions, data can be
retained by the lowest power consumption.
■ Switching to the Stop Mode
When "1" is written to the STP bit of the low-power consumption mode control register (LPMCR),
switching to the stop mode occurs.
●
Data retention function
In the stop mode, the contents of the dedicated registers, such as accumulators, and the built-in RAM are
retained.
●
Operation during an interrupt request
Writing "1" in the STP bit of the low-power consumption mode control register (LPMCR) does not trigger
a switch to the stop mode.
●
Status of pins
Whether the external pins in the stop mode retain the state they had immediately before switching to the
stop mode or go to the high-impedance state can be controlled by the SPL bit of the low-power
consumption mode control register (LPMCR).
