MC68HC11A8TS/D
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
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
CONFIG
— COP, ROM, EEPROM Enables
