Read anytime. Write anytime if EEPGM = 0 and PROTLCK = 0.
EEPGM is cleared automatically after the program/erase cycles are
finished when AUTO is set.
Read anytime. Write anytime if EEPGM = 0.
Read anytime. Write anytime if EEPGM = 0.
Read anytime. Write anytime if EEPGM = 0.
BYTE and ROW have no effect when ERASE = 0
For More Information On This Product,
0 = EEPROM can be bulk erased.
1 = EEPROM is protected from being bulk or row erased.
0 = Automatic clear of EEPGM is disabled.
1 = Automatic clear of EEPGM is enabled.
0 = Bulk or row erase is enabled.
1 = One byte or one aligned word erase only.
0 = Erase entire EEPROM array.
1 = Erase only one 32-byte row.
