EEPROG — EEPROM Control
RESET:
BULKP
Bit 7

.
BULKP — Bulk Erase Protection
AUTO — Automatic shutdown of program/erase operation.
BYTE — Byte and Aligned Word Erase
ROW — Row or Bulk Erase (when BYTE = 0)

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
If BYTE = 1 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.
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.
