Read anytime. Write anytime if EEPGM = 0 and PROTLCK = 0.
Read anytime. Write anytime if EEPGM = 0.
Read anytime. Write anytime if EEPGM = 0.
BYTE and ROW have no effect when ERASE = 0
If BYTE = 1 and test mode is not enabled, only the location specified
by the address written to the programming latches will be erased. The
operation will be a byte or an aligned word erase depending on the
size of written data.
Read anytime. Write anytime if EEPGM = 0.
Configures the EEPROM for erasure or programming.
For More Information On This Product,
0 = EEPROM can be bulk erased.
1 = EEPROM is protected from being bulk or row erased.
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.
0 = EEPROM configuration for programming.
1 = EEPROM configuration for erasure.
