To Execute the Program
To Execute the Program
Use this step-by-step procedure to program the MC68HC711E9 device.
Step 1
Step 2
Apply power to the programmer board by moving the +5-V switch to the ON position. From a DOS
command line prompt, start PCbug11this way:
PCbug11 only supports COM ports 1 and 2. If the proper connections are made and you have a
high-quality cable, you should quickly get a 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.

C:\PCBUG11\ > PCBUG11 –E PORT = 1 with the E9PGMR connected to COM1
C:\PCBUG11\ > PCBUG11 –E PORT = 2 with the E9PGMR connected to COM2
Enabling the Security Feature on the MC68HC711E9 Devices with PCbug11 on the M68HC711E9PGMR, Rev. 0.1
Before applying power to the programming board, connect the M68HC711E9PGMR serial port P2
to one of your PC COM ports with a standard 25-pin RS-232 cable. Do not use a null modem cable
or adapter which swaps the transmit and receive signals between the connectors at each end of
the cable.
Place the MC68HC711E9 part in the PLCC socket on your board.
Insert the part upside down with the notched corner pointing toward the red power LED.
Make sure both S1 and S2 switches are turned off.
Apply +5 volts to +5-V, +12 volts (at most +12.5 volts) to V
programmer board’s power connector, P1. The remaining TXD/PD1 and RXD/PD0 connections
are not used in this procedure. They are for gang programming MC68HC711E9 devices, which is
discussed in the M68HC711E9PGMR Manual. You cannot gang program with PCbug11.
Ensure that the "remove for multi-programming" jumper, J1, below the +5-V power switch has a
fabricated jumper installed.
