ODD —Program Odd Rows in Half of EEPROM (TEST)
EVEN —Program Even Rows in Half of EEPROM (TEST)
LVPI —Low Voltage Programming Inhibit
LVPI can be read at any time and writes to LVPI have no meaning nor effect. LVPI is set if LVPEN bit
in BPROT register equals one and the LVPI circuit detects that V_DD has fallen below a safe operating
voltage. Once set, LVPI is cleared when V_DD returns to a safe operating voltage or if LVPEN bit in
BPROT register is cleared. If LVPEN equals zero, then LVPI is always zero and has no meaning nor
effect.
0 = EEPROM programming enabled
1 = EEPROM programming disabled
BYTE —Byte/Other EEPROM Erase Mode
0 = Row or bulk erase mode used
1 = Erase only one byte of EEPROM
ROW —Row/All EEPROM Erase Mode (only valid when BYTE = 0)
0 = All 640 bytes of EEPROM erased
1 = Erase only one 16-byte row of EEPROM

ERASE —Erase/Normal Control for EEPROM
0 = Normal read or program mode
1 = Erase mode
EELAT —EEPROM Latch Control
0 = EEPROM address and data bus configured for normal reads
1 = EEPROM address and data bus configured for programming or erasing
EEPGM —EEPROM Program Command
0 = Program or erase voltage switched off to EEPROM array
1 = Program or erase voltage switched on to EEPROM array

NOTE
Block protect register bits can be written to zero (protection disabled) only once
within 64 cycles of a reset in normal modes, or at any time in special modes. Block
protect register bits can be written to one (protection enabled) at any time.
BULKP —Bulk Erase of EEPROM Protect
0 = EEPROM can be bulk erased normally
1 = EEPROM cannot be bulk or row erased
