EEOFF — EEPROM Power-Off
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.
1 = Disable EEPROM array
0 = Enable EEPROM array
EERAS[1:0] — Erase/Program Mode Select Bits
These read/write bits set the erase modes. Reset clears these bits.

EELAT — EEPROM Latch Control
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.
1 = Buses configured for EEPROM program or erase operation
0 = Buses configured for normal operation
AUTO — Automatic termination of program/erase cycle
When AUTO is set, EEPGM is cleared automatically after the
program/erase cycle is terminated by the internal timer.
(See note D for 5.9.1 EEPROM Programming
Erasing.)
0 = Automatic clear of EEPGM is disabled
1 = Automatic clear of EEPGM is enabled
