4.5.4
There are three types of ERASE operation mode (see Table 4-1): byte erase, block erase, and
bulk erase.
Note:
4.5.5
To program the content of EEPROM, set EELAT bits, write data to the desired address, and set
the EEPGM bit. After the required programming delay t
resets EEPGM. During a programming operation, any access to the EEPROM will return $FF. To
program a second byte, EELAT must be cleared before it is set, or the programming will have no
effect.

1) To perform byte erase operation, set EELAT=1, EER1=0, and EER0=1, write
2) To perform block erase operation, set EELAT=1, EER1=1, and EER0=0,
3) To perform bulk erase operation, set EELAT=1, EER1=1, and EER0=0, write
any data to the address to be erase, and set EEPGM for a time t
write any data to any address in the block, and set EEPGM for a time
t
any data to any address in the EEPROM map, and set EEPGM for a time
t
Erase operation to any part of block 2 is not possible if the EEPRT bit is programmed
to “0”.
