Programming Procedure
Programming Procedure
Once you have obtained PCbug11, use this step-by-step procedure to program your MC68HC711E9 part.
Step 1
Also take note of P4 connector pin 18. In step 5, you will connect a +12-volt (at most +12.5 volts)
programming voltage through a 100-Ω current limiting resistor to the XIRQ pin. Do not connect this
programming voltage until you are instructed to do so in step 5.
Step 2
PCbug11 only supports COM ports 1 and 2. If you have made the proper connections and have a high
quality cable, you should quickly get a PCbug11 command prompt. If you do receive a Comms fault error,
check your cable and board connections. Most PCbug11 communications problems can be traced to
poorly made cables or bad board connections.
Step 3
CONTROL BASE HEX
Step 4
Step 5
You are now ready to download your program into the EPROM.
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.

Before applying power to the EVBU, remove the jumper from J7 and place it across J3 to ground
the MODB pin.
Place a jumper across J4 to ground the MODA pin. This will force the EVBU into special bootstrap
mode on power up.
Remove the resident MC68HC11E9 MCU from the EVBU.
Place your MC68HC711E9 in the open socket with the notched corner of the part aligned with the
notch on the PLCC socket.
Connect the EVBU to one of your PC COM ports. Apply +5 volts to V
power connector of your EVBU.
From a DOS command line prompt, start PCbug11 with
PCbug11 defaults to base 10 for its input parameters; change this to hexadecimal by typing
You must declare the addresses of the EPROM array to PCbug11. To do this, type:
EPROM D000 FFFF
Connect +12 volts (at most +12.5 volts) through a 100-Ω current limiting resistor to P4 connector
pin 18, the XIRQ* pin.
At the PCbug11 command prompt type: LOADS C:\MYPROG\ISHERE.S19
C:\PCBUG11\> PCBUG11 –E PORT = 1 with the EVBU connected to COM1
C:\PCBUG11\> PCBUG11 –E PORT = 2 with the EVBU connected to COM2
