To Execute the Program
To Execute the Program
Once you have obtained PCbug11, use this step-by-step procedure.
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:
PCbug11only supports COM ports 1 and 2.
PCbug11 defaults to base ten for its input parameters.
Change this to hexadecimal by typing: CONTROL BASE HEX
Clear the block protect register (BPROT) to allow programming of the MC68HC811E2 EEPROM.
At the PCbug11 command prompt, type: MS 1035 00
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
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.
Enabling the Security Feature on M68HC811E2 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
Place your MC68HC811E2 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 volts and ground to GND on the programmer board’s power connector, P1.
