Step 6
Erase the CONFIG to allow programming of NOSEC bit (bit 3). It is also recommended to program the
EEPROM at this point before programming the CONFIG register. Refer to the engineering bulletin
Programming MC68HC811E2 Devices with PCbug11 and the M68HC711E9PGMR, Freescale document
number EB184.
At the PCbug11command prompt, type: EEPROM ERASE BULK 103F
Step 7
You are now ready to enable the security feature on the MCHC811E2.
At the PCbug11 command prompt, type: MS 103F 05
The value $05 assumes the EEPROM is to be mapped from $0800 to $0FFF.
Step 8
After the programming operation is complete, verifying the CONFIG on the MCHC811E2 is not possible
because in bootstrap mode the default value is always forced.
Step 9
The part is now in secure mode and whatever code you loaded into EEPROM will be erased if you tried
to bring the microcontroller up in either expanded mode or bootstrap mode. The microcontroller will work
properly in the secure mode only in single chip mode.

Enabling the Security Feature on M68HC811E2 Devices with PCbug11 on the M68HC711E9PGMR, Rev. 0.1
If the part is placed in bootstrap mode or expanded mode, the code in
EEPROM and RAM will be erased the microcontroller can be reused.
