EEPROM
Functional description
Low power modes The WAIT and STOP instructions can put the MCU in low power
consumption standby modes.
WAIT mode
The WAIT instruction does not affect the EEPROM. It is possible to
program the EEPROM and put the MCU in WAIT mode. However, if the
EEPROM is inactive, power can be reduced by setting the EEOFF bit
before executing the WAIT instruction.
STOP mode
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 automatically be turned off. However, the EEPGM bit will
remain set. When STOP mode is terminated, if EEPGM is still set, the
high voltage will automatically be turned back on. Program/erase time
will need to be extended if program/erase is interrupted by entering
STOP mode.
The module requires a recovery time t_EESTOP to stabilize after leaving
STOP mode. Attempts to access the array during the recovery time will
result in unpredictable behavior.
