EEPROM-1 Memory
Technical Data
100
NOTE:
EELAT — EEPROM-1 Latch Control
AUTO — Automatic termination of program/erase cycle
EEPGM — EEPROM-1 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.
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.
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 542)
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 = Buses configured for EEPROM-1 programming or erase
0 = Buses configured for normal operation
1 = Automatic clear of EEPGM is enabled
0 = Automatic clear of EEPGM is disabled
1 = EEPROM-1 programming/erasing power switched on
0 = EEPROM-1 programming/erasing power switched off
