To Execute the Program

To Execute the Program

Once you have obtained PCbug11, use this step-by-step procedure.

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 your MC68HC811E2 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 volts and ground to GND on the programmer boardâs power connector, P1.

Applying voltage to the VPP pin is not necessary.

Step 2

Apply power to the programmer board by moving the +5-volt switch to the ON position.

From a DOS command line prompt, start PCbug11 this way:

â¢ C:\PCBUG11\> PCBUG11 âA PORT = 1 when the E9PGMR connected to COM1 or

â¢ C:\PCBUG11\> PCBUG11 âA PORT = 2 when the E9PGMR connected to COM2

PCbug11only supports COM ports 1 and 2.

Step 3

PCbug11 defaults to base ten 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 MC68HC811E2 EEPROM.

At the PCbug11 command prompt, type: MS 1035 00

Step 5

PCbug11 defaults to a 512-byte EEPROM array located at $B600. This must be changed since the

EEPROM is, by default, located at $F800 on the MC68HC811E2.

At the PCbug11 command prompt, type: EEPROM 0

Then type: EEPROM F800 FFFF

Then type: EEPROM 103F 103F

This assumes you have not relocated the EEPROM by previously reprogramming the upper 4 bits of the

CONFIG register. But if you have done this and your S records reside in an address range other than

$F800 to $FFFF, you will need to first relocate the EEPROM.
