Step 6
After the programming operation is complete, PCbug11 will display this message
Total bytes loaded: $xxxx
Total bytes programmed: $yyyy
Substitute the name of your program into the command above. Use a full path name if your program is
not located in the same directory as PCbug11.
If the verify operation fails, a list of addresses which did not program correctly is displayed. Should this
occur, you probably need to erase your part more completely. To do so, allow the MC68HC711E9 to sit
for at least 45 minutes under an ultraviolet light source. Attempt the programming operation again. If you
have purchased devices in plastic packages (one-time programmable parts), you will need to try again
with a new, unprogrammed device.

You should now remove the programming voltage from P4 connector pin 18, the XIRQ* pin.
Each ORG directive in your assembly language source will cause a pair of these lines to be
generated. For this operation, $yyyy will be incremented by the size of each block of code
programmed into the EPROM of the MC68HC711E9.
PCbug11 will display the above message whether or not the programming operation was
successful. As a precaution, you should have PCbug11 verify your code.
At the PCbug11 command prompt type: VERF C:\MYPROG\ISHERE.S19
