9-eeprom-2
MOTOROLA
NOTE:
EERAS1 and EERAS0 — Erase Bits
EELAT — EEPROM Latch Control
EEPGM — EEPROM Program/Erase Enable
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.
Freescale Semiconductor, Inc.
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 cannot be cleared if
EEPGM is still set. Reset clears this bit.
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.
