5.11.1 EEPROM Control Register
Technical Data
78
Address:
The STOP instruction reduces the EEPROM power consumption to a
minimum. The STOP instruction should not be executed while the
programming and erasing sequence is in progress.
If stop mode is entered while EELAT and EEPGM is set, the
programming sequence will be stopped and the programming voltage to
the EEPROM array removed. The programming sequence will be
restarted after leaving stop mode; access to the EEPROM is only
possible after the programming sequence has completed.
If stop mode is entered while EELAT and EEPGM is cleared, the
programming sequence will be terminated abruptly.
In either case, the data integrity of the EEPROM is not guaranteed.
Four I/O registers and three non-volatile registers control program,
erase, and options of the EEPROM array.
This read/write register controls programming/erasing of the EEPROM
array.
