PCbug11 command prompt. If you do receive a Comms fault error,
check the cable and board connections. Most PCbug11 communications
problems can be traced to poorly made cables or bad board
connections.
Step 3
PCbug11 defaults to base 10 for its input parameters.
Change this to hexadecimal by typing: CONTROL BASE HEX.
Step 4
Clear the block protect register (BPROT) to allow programming of the
MC68HC711E9 EEPROM.
At the PCbug11 command prompt, type: MS 1035 00.
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.
