Advance Information

EERAS1 and EERAS0 — Erase/Program Mode Select Bits
EELAT — EEPROM-2 Latch Control
AUTO — Automatic Termination of Program/Erase Cycle
EEPGM — EEPROM-2 Program/Erase Enable
X = don’t care
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-2 array. EELAT cannot 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
page 458)
This read/write bit enables the internal charge pump and applies the
programming/erasing voltage to the EEPROM-2 array if the EELAT
bit is set and a write to a valid EEPROM-2 location has occurred.
Reset clears the EEPGM bit.
