BULKP — Bulk Erase Protection
0 = EEPROM can be bulk erased.
1 = EEPROM is protected from being bulk or row erased.
Read anytime. Write anytime if EEPGM = 0 and PROTLCK = 0.
BYTE — Byte and Aligned Word Erase
0 = Bulk or row erase is enabled.
1 = One byte or one aligned word erase only.
Read anytime. Write anytime if EEPGM = 0.
ROW — Row or Bulk Erase (when BYTE = 0)
0 = Erase entire EEPROM array.
1 = Erase only one 32-byte row.
Read anytime. Write anytime if EEPGM = 0.
BYTE and ROW have no effect when ERASE = 0
