Programming Procedure
Step 1
Step 2
264
Once you have obtained PCbug11, use this step-by-step procedure to
program your MC68HC711E9 part.
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.

For More Information On This Product,
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
From a DOS command line prompt, start PCbug11 with
– C:\PCBUG11\> PCBUG11 –E PORT = 1
– C:\PCBUG11\> PCBUG11 –E PORT = 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.
