NOTE:
NOTE:
You are now ready to enable the security feature on the MCHC711E9.
At the PCbug11 command prompt type: MS 103F 05.
After the programming operation is complete, verifyng the CONFIG on
the MCHC711E9 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.
It is important to note that the microcontroller will work properly in secure
mode only in single chip mode.
If the part is placed in bootstrap or expanded, the code in EEPROM and
RAM will be erased and the microcontroller cannot be reused. The
security software will constantly read the NOSEC bit and lock the part.
