Technical Data
NOTE:

Address:
EEPGM — EEPROM Program/Erase Enable Bit
Writing logic 0s to both the EELAT and EEPGM bits with a single
instruction will clear EEPGM only to allow time for the removal of high
voltage.
The EEPROM non-volatile register (EENVR2) and array control register
(EEACR2) are shown in

Write:
This read/write bit enables the internal charge pump and applies the
programming/erasing voltage to the EEPROM array if the EELAT bit
is set and a write to a valid EEPROM location has occurred. Reset
clears the EEPGM bit.
