6.4.8 Low-Power Modes
6.4.8.1 Wait Mode
6.4.8.2 Stop Mode

MOTOROLA
—
Rev. 4.0
The following subsections describe the low-power modes.
The WAIT instruction does not affect the EEPROM. It is possible to
program the EEPROM while the MCU is in wait mode. However, if the
EEPROM is inactive, power can be reduced by setting the EEOFF bit
before executing the WAIT instruction.
The STOP instruction reduces the EEPROM power consumption to a
minimum. The STOP instruction should not be executed while the high
voltage is turned on (EEPGM = 1).
If stop mode is entered while program/erase is in progress, high voltage
will be turned off automatically. However, the EEPGM bit will remain set.
When stop mode is terminated and if EEPGM is still set, the high voltage
will be turned back on automatically. Program/erase time will need to be
extended if program/erase is interrupted by entering stop mode.
The module requires a recovery time, t
stop mode (see
during the recovery time will result in unpredictable behavior.
