EEPROM-2 Memory
7.5 EEPROM-2 Register Descriptions
Four I/O registers and three nonvolatile registers control program, erase and options of the EEPROM-2
array.
7.5.1 EEPROM-2 Control Register
This read/write register controls programming/erasing of the array.
Bit 7— Unused bit
EEOFF — EEPROM-2 power down
EERAS1 and EERAS0 — Erase/Program Mode Select Bits
EELAT — EEPROM-2 Latch Control
92
This read/write bit is software programmable but has no functionality.
This read/write bit disables the EEPROM-2 module for lower power consumption. Any attempts to
access the array will give unpredictable results. Reset clears this bit.
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.
1 = Disable EEPROM-2 array
0 = Enable EEPROM-2 array
1 = Buses configured for EEPROM-2 programming or erase operation
0 = Buses configured for normal operation
