EECPM — Charge Pump Monitor Enable
BULKP — Bulk Erase Protection
BYTE — Byte and Aligned Word Erase
ROW — Row or Bulk Erase (when BYTE = 0)
ERASE — Erase Control
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.
