To Execute the Program
Step 5
The CONFIG register defaults to hexadecimal 103F on the MC68HC711E9. PCBUG11 needs adressing
parameters to allow programming of a specific block of memory so the following parameter must be given.
At the PCbug11 command prompt, type: EEPROM 0.
Then type: EEPROM 103F 103F.
Step 6
Erase the CONFIG to allow byte programming.
At the PCbug11 command prompt, type: EEPROM ERASE BULK 103F.
Step 7
You are now ready to download the program into the EEPROM and EPROM.
At the PCbug11command prompt, type: LOADSC:\MYPROG\MYPROG.S19.
For more details on programming the EPROM, read the engineering bulletin Programming
MC68HC711E9 Devices with PCbug11 and the M68HC11EVB, Freescale document number EB187.
Step 8
You are now ready to enable the security feature on the MCHC711E9.
At the PCbug11 command prompt type: MS 103F 05.
Step 9
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.
Step 10
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.
NOTE
It is important to note that the microcontroller will work properly in secure
mode only in single chip mode.
NOTE
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.
