ODD — Program Odd Rows in Half of EEPROM (Test) Bit
EVEN — Program Even Rows in Half of EEPROM (Test) Bit
ELAT — EPROM/OTPROM Latch Control Bit

EELAT — EEPROM Latch Control Bit
1. MC68HC711E9 only
For the MC68HC711E9, EPGM enables the high voltage necessary for both
EPROM/OTPROM and EEPROM programming.
For MC68HC711E9, ELAT and EELAT are mutually exclusive and cannot both
equal 1.
This bit overrides the ROW bit.
If BYTE is 1, ROW has no meaning.

Write:
0 = EPROM address and data bus configured for normal reads
1 = EPROM address and data bus configured for programming
0 = Row or bulk erase
1 = Erase only one byte
0 = Bulk erase
1 = Row erase
0 = Normal read or program mode
1 = Erase mode
0 = EEPROM address and data bus configured for normal reads and cannot
1 = EEPROM address and data bus configured for programming or erasing
