TECHNICAL DATA
3
of ROM and EEPROM in the memory map, as well as enabling the COP watchdog
system. A security feature to protect data in the EEPROM and RAM is also available
on mask programmed MC68HC11A8s.
Bits 7, 6, 5, and 4 — Not Implemented
These bits are always read as zero.
NOSEC — Security Mode Disable Bit
This bit is only implemented if it is specifically requested at the time mask ROM infor-
mation is submitted. When this bit is not implemented it always reads one.
When RAM and EEPROM security are required, the NOSEC bit can be programmed
to zero to enable the software anti-theft mechanism. When clear, the NOSEC bit pre-
vents the selection of expanded multiplexed operating modes. If the MCU is reset in
the special bootstrap operating mode while NOSEC is zero, EEPROM, RAM, and
CONFIG are erased before the loading process continues.
0 = Enable Security Mode
1 = Disable Security Mode
NOCOP — COP System Disable
0 = COP Watchdog System Enabled
1 = COP Watchdog System Disabled
ROMON — Enable On-Chip ROM
When this bit is clear, the 8K ROM is disabled, and that memory space becomes ex-
ternally accessed space. In the single-chip operating mode, the internal 8K ROM is en-
abled regardless of the state of the ROMON bit.
EEON — Enable On-Chip EEPROM
When this bit is clear, the 512-byte EEPROM is disabled, and that memory space be-
comes externally accessed space.
3.5.3.1 Programming and Erasure of the CONFIG Register
Since the CONFIG register is implemented with EEPROM cells, special provisions
must be made to erase and program this register. The normal EEPROM control bits in
the PPROG register are used for this purpose. Programming follows the same proce-
dure as programming a byte in the 512-byte EEPROM except the CONFIG register
address is used. Erase also follows the same procedure as that used for the EEPROM
except that only bulk erase can be used on the CONFIG register. When the CONFIG
register is erased, the 512-byte EEPROM array is also erased. Be sure to check the
Technical Summary for the particular MC68HC11 Family member you are using.
