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.).
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
Freescale Semiconductor
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.
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 be programmed
1 = EEPROM address and data bus configured for programming or erasing and cannot be read
