8-Bit Microcontrollers

Freescale Semiconductor 

ERASE — Erase/Normal Control for EEPROM

0 = Normal read or program mode

1 = Erase mode

EELAT — EEPROM Latch Control

0 = EEPROM address and data bus configured for normal reads

1 = EEPROM address and data bus configured for programming or erasing

EEPGM — EEPROM Program Command

0 = Programming or erase voltage switched off to EEPROM array

1 = Programming or erase voltage switched on to EEPROM array

CONFIG — COP, ROM, EEPROM Enables

NOTE

The bits of this register are implemented with EEPROM cells. Programming and

erasing follow normal EEPROM procedures. The erased state of CONFIG is $0F.

A new value is not readable until after a subsequent reset sequence. CONFIG can

only be programmed or erased in special modes.

NOSEC — EEPROM Security Disable

NOSEC has no meaning unless the security mask option was specified before the MCU was manufac-

tured.

0 = Security enabled (available as a mask option on MC68HC11A8 only)

1 = Security disabled

NOCOP — COP system disable

Refer to 3 Resets and Interrupts.

ROMON — ROM Enable

Refer to 2 Operating Modes and Memory Maps.

EEON — EEPROM Enable

0 = EEPROM is removed from the memory map

1 = EEPROM is present in the memory map
