2.4.3 EPROM and EEPROM Programming Control Register
The EPROM and EEPROM programming control register (PPROG) enables the EPROM programming
voltage and controls the latching of data to be programmed.
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
BYTE — Byte/Other EEPROM Erase Mode Bit
ROW — Row/All EEPROM Erase Mode Bit
ERASE — Erase Mode Select Bit
EELAT — EEPROM Latch Control Bit
EPGM —EPROM/OTPROM/EEPROM Programming Voltage Enable Bit

When ELAT = 1, writes to EPROM cause address and data to be latched and the EPROM/OTPROM
cannot be read. ELAT can be read any time. ELAT can be written any time except when EPGM = 1;
then the write to ELAT is disabled.
For the MC68HC711E9:

EPGM can be read any time and can be written only when ELAT = 1 (for EPROM/OTPROM
programming) or when EELAT = 1 (for EEPROM programming).
0 = EPROM address and data bus configured for normal reads
1 = EPROM address and data bus configured for programming
0 = Programming voltage to EPROM/OTPROM/EEPROM array disconnected
1 = Programming voltage to EPROM/OTPROM/EEPROM array connected
For MC68HC711E9, PPROG is also the EEPROM programming control register.
For the MC68HC711E20, EPROM programming is controlled by the EPROG register and
EEPROM programming is controlled by the PPROG register.
a. EPGM enables the high voltage necessary for both EEPROM and EPROM/OTPROM
b. ELAT and EELAT are mutually exclusive and cannot both equal 1.
