EEOFF — EEPROM Power-Off
EERAS[1:0] — Erase/Program Mode Select Bits
EELAT — EEPROM Latch Control
AUTO — Automatic termination of program/erase cycle
X = don’t care
This read/write bit disables the EEPROM module for lower power
consumption. Any attempts to access the array will give unpredictable
results. Reset clears this bit.
These read/write bits set the erase modes. Reset clears these bits.
This read/write bit latches the address and data buses for
programming the EEPROM array. EELAT can not be cleared if
EEPGM is still set. Reset clears this bit.
When AUTO is set, EEPGM is cleared automatically after the
program/erase cycle is terminated by the internal timer.
(See note D for
Erasing.)
