NOTE:
You are now ready to enable the security feature on the MCHC811E2.
The value $05 assumes the EEPROM is to be mapped from $0800 to
$0FFF.
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.
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.
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.
