A program or erase operation should follow the sequence below:
1. Write BYTE, ROW and ERASE to the desired value; write EELAT = 1
2. Write a byte or an aligned word to an EEPROM address
3. Write EEPGM = 1
4. Wait for programming (t
PROG
) or erase (t
ERASE
) delay time
5. Write EEPGM = 0
6. Write EELAT = 0
It is possible to program/erase more bytes or words without intermediate EEPROM reads, by jumping
from step 5 to step 2.
