2.5.1.2 EPROM and EEPROM Programming Control Register
The EPROM and EEPROM programming control register (PPROG) selects and controls the EEPROM
programming function. Bits in PPROG enable the programming voltage, control the latching of data to be
programmed, and select the method of erasure (for example, byte, row, etc.).

Figure 2-17. EPROM and EEPROM Programming
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
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.
0 = EPROM address and data bus configured for normal reads
1 = EPROM address and data bus configured for programming
BYTE — Byte/Other EEPROM Erase Mode Bit
This bit overrides the ROW bit.
0 = Row or bulk erase
1 = Erase only one byte
ROW — Row/All EEPROM Erase Mode Bit
If BYTE is 1, ROW has no meaning.
0 = Bulk erase
1 = Row erase
