Programming MC68HC811E2 Devices with PCbug11 M68HC711E9PGMR
John Bodnar Austin, Texas
Introduction
PCbug11 software, needed along with M68HC711E9PGMR program MC68HC811E2 devices, available from download section Microcontroller Worldwide site www.mcu.motsps.com. Retrieve file pcbug342.exe self-extracting archive) from MCU11 directory. Some Motorola evaluation board products also shipped with PCbug11.
NOTE:
specific information about PCbug11 commands, appropriate sections PCbug11 User's Manual (part number M68PCBUG11/D2), which available from Motorola Literature Distribution Center, well Worldwide www.mcu.motsps.com. file also software download system called pcbug11.pdf.

Once have obtained PCbug11, this step-by-step procedure program your MC68HC811E2 part.
Step
Freescale Semiconductor, Inc.
Before applying power programming board, connect M68HC711E9PGMR serial port your ports with standard 25-pin RS-232 cable. null modem cable adapter which swaps transmit receive signals between connectors each cable. Place your MC68HC811E2 part PLCC socket your board. Insert part upside down with notched corner pointing toward power LED. Make sure both switches turned off. Apply volts +5-V, volts most +12.5 volts) VPP, ground your programmer board's power connector, remaining TXD/PD1 RXD/PD0 connections used this procedure. They gang programming MC68HC711E9 devices, which discussed M68HC711E9PGMR Manual. cannot gang program with PCbug11.
Step
Apply power your programmer board moving +5-V switch position. From command line prompt, start PCbug11 this way: C:\PCBUG11\ PCBUG11 PORT with E9PGMR connected COM1 C:\PCBUG11\ PCBUG11 PORT with E9PGMR connected COM2

PCbug11 only supports ports proper connections made have high quality cable, should quickly PCbug11 command prompt. receive "Comms fault" error, check your cable board connections. Most PCbug11 communications problems traced poorly made cables board connections.
Step
PCbug11 defaults base input parameters. Change this hexadecimal typing: CONTROL BASE HEX.

Step
Clear block protect register (BPROT) allow programming MC68HC811E2 EEPROM. PCbug11 command prompt, type: 1035
Step
PCbug11 defaults 512-byte EEPROM array located $B600. This must changed since EEPROM default, located $F800 MC68HC811E2. PCbug11 command prompt, type: EEPROM Then type: EEPROM F800 FFFF. This assumes have relocated EEPROM previously reprogramming upper bits CONFIG register. have done this, your S-records reside address range other than $F800 $FFFF, will need first relocate EEPROM. When MC68HC811E2 powers bootstrap mode, EEPROM forced addresses from $F800 $FFFF. relocate EEPROM bootstrap mode directly modifying CONFIG register. example, CONFIG register been reprogrammed relocate EEPROM address range from $0800 $0FFF, this should typed PCbug11 command prompt: 103F

other address ranges, would replace following 103F with value between with exception cannot relocate EEPROM addresses from $B800 $BFFF bootstrap mode because bootstrap code resides there always read write precedence over internal EEPROM. that have done this, simply replace arguments second PCbug11 EEPROM instruction above with appropriate values. example here CONFIG register reprogrammed $0F, type EEPROM 0800 0FFF PCbug11 command prompt.

Step
Erase EEPROM allow byte programming your code downloaded. PCbug11command prompt, type: EEPROM ERASE BULK F800. Once again, remember substitute correct value F800 command above relocated EEPROM changing upper bits CONFIG register.
Step
ready download your program into EEPROM. PCbug11 command prompt, type: LOADS C:\MYPROG\ISHERE.S19 Substitute name your program into command above. full path name your program located same directory PCbug11.

After programming operation complete, PCbug11 displays this message: Total bytes loaded: $xxxx Total bytes programmed: $yyyy pair these lines will displayed each block code your S-record file. more specifically, each directive your assembly language source will cause pair these lines generated. this operation, $yyyy will incremented size each block code programmed into EEPROM MC68HC811E2.

PCbug11 displays above message whether programming operation successful.
precaution, should have PCbug11 verify your code. PCbug11command prompt, type: VERF C:\MYPROG\ISHERE.S19 Substitute name your program into command above. full path name your program located same directory PCbug11. verify operation fails, list addresses which program correctly displayed. Should this occur, several things wrong: clear block protect register. Return step Your part erase properly. PCbug11 command prompt, type: EEPROM DELAY This will increase EEPROM erase delay timing. After increasing delay timing, back step Your part have damaged EEPROM array. this case, will need MC68HC811E2 device.
