    MC68HC912BL16TS/D
    EECPRD — Charge Pump Ramp Disable
    Known to enhance write/erase endurance of EEPROM cells.
    0 = Charge pump is turned on progressively during program/erase.
    1 = Disable charge pump controlled ramp up.
    EECPM — Charge Pump Monitor Enable
    0 = Normal operation.
    1 = Output the charge pump voltage on the IRQ/VPP pin.
    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
    If BYTE = 1 and test mode is not enabled, only the location specified by the address written to the pro-
    gramming latches will be erased. The operation will be a byte or an aligned word erase depending on
    the size of written data.
    ERASE — Erase Control
    0 = EEPROM configuration for programming or reading.
    1 = EEPROM configuration for erasure.
    Read anytime. Write anytime if EEPGM = 0.
    Configures the EEPROM for erasure or programming.
    When test mode is not enabled and unless BULKP is set, erasure is by byte, aligned word, row or bulk.
    EELAT — EEPROM Latch Control
    0 = EEPROM set up for normal reads.
    1 = EEPROM address and data bus latches set up for programming or erasing.
    Read anytime. Write anytime if EEPGM = 0.
    NOTE
    When EELAT is set, the entire EEPROM is unavailable for reads, therefore, no pro-
