To Execute the Program

To Execute the Program

Use this step-by-step procedure to program the MC68HC711E9 device.

Step 1

â¢ 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.

â¢ Place the MC68HC711E9 part in the PLCC socket on your board.

â¢ Insert the part upside down with the notched corner pointing toward the red power LED.

â¢ Make sure both S1 and S2 switches are turned off.

â¢ Apply +5 volts to +5-V, +12 volts (at most +12.5 volts) to VPP, and ground to GND on your

programmer boardâs 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.

â¢ Ensure that the "remove for multi-programming" jumper, J1, below the +5-V power switch has a

fabricated jumper installed.

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:

C:\PCBUG11\ > PCBUG11 âE PORT = 1 with the E9PGMR connected to COM1

or

C:\PCBUG11\ > PCBUG11 âE PORT = 2 with the E9PGMR connected to COM2

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.
