EERAS1 and EERAS0 — Erase/Program Mode Select Bits
These read/write bits set the erase modes. Reset clears these bits.

EELAT — EEPROM-1 Latch Control
This read/write bit latches the address and data buses for
programming the EEPROM-1 array. EELAT cannot be cleared if
EEPGM is still set. Reset clears this bit.
1 = Buses configured for EEPROM-1 programming 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 EEPROM-1 Programming on page 66, EEPROM-1
Erasing on page 67 and EEPROM Memory Characteristics on
page 458)
1 = Automatic clear of EEPGM is enabled
0 = Automatic clear of EEPGM is disabled
EEPGM — EEPROM-1 Program/Erase Enable
This read/write bit enables the internal charge pump and applies the
programming/erasing voltage to the EEPROM-1 array if the EELAT
bit is set and a write to a valid EEPROM-1 location has occurred.
Reset clears the EEPGM bit.
1 = EEPROM-1 programming/erasing power switched on
0 = EEPROM-1 programming/erasing power switched off
