3.6.2.1 PPROG — EEPROM programming control register
MC68HC11P2 — Rev 1.0
EEPROM programming
(PPROG)
NOTE:
Writes to EEPROM addresses are inhibited while EEPGM is one. A write
to a different EEPROM location is prevented while a program or erase
operation is in progress.
ODD — Program odd rows in half of EEPROM (Test)
EVEN — Program even rows in half of EEPROM (Test)
Bit 5 — Not implemented; always reads zero.
BYTE — EEPROM byte erase mode
ROW — EEPROM row/bulk erase mode (only valid when BYTE = 0)
ERASE — Erase/normal control for EEPROM
Freescale Semiconductor, Inc.
If both ODD and EVEN are set to one then all odd and even rows in
half of the EEPROM will be programmed with the same data, within
one programming cycle.
