MC6809 In-Circuit-Emulator, ICE-JH Plans and Software included Laptop in photos not included. Hardware proto-type is for illustration and is not included. This is a low cost solution for MC6809 system development/check out. IN-CIRCUIT-EMULATOR FOR MC68009 (ICE-JH) Copyright 2015 by: John E. Hieber I. ICE-JH uses two Z80 PIO's to provide the electrical interface. The control logic/software resides in an IBM compatible computer with a serial PORT and a bi-directional parallel PORT. Desktop or Laptop running DOS with 640 KB of memory. II. ICE-JH allows RAM memory to be written and read. It allows ROM memory to be read. It allow I/O Ports to be written and read. It also has a disassemble memory function. Static memory. May read and write DRAM but depends on target. III. The ICE-JH menu of commands is as follows: Command field are delimited by space(s), fields are in Hex Invalid commands are ignored (no error displayed) Space bar will pause/resume, Enter will abort Set Breakpoint, B ADDR1 ... ADDRn Clear Breakpoint, BC n (n = 0, clear all) Display Breakpoint, BD Display/Dump memory, D ADDR1 ADDR2 Download Hex File, DL Filename.HEX SADDR (SADDR Optional) Fill memory, F ADDR1 ADDR2 DATA Go Exec Code to BKPT, G (Start At PC) Go Exec Code to BKPT, GB ADDR (Start At ADDR) Go Exec Single Step, GS (Start At PC) Show REGs at Step, R (displays REGS/FLAGS) Change REG/FLAG, R rr DATA (rr is REG/FLAG name) Search memory (match), S ADDR1 ADDR2 DATA Set signal delay, T (no. of 0.025 msec ticks) Set R/W Watchpoint, W ADDR1 ... ADDRn Clear Watchpoint, WC n (n = 0, clear all) Display Watchpoint, WD Configure PORT Addr X IV. The execute function includes Single step and Break points. Note break points are possible at ROM memory addresses. V. The Wiring Schematic for ICE-JH and the PC software is included with this Tech Note. Both source (ICE-JH.BAS) and executable (ICE-JH.EXE) files are included. VI. Required files(included contain opcodes): OPC10INS.TXT OPC11INS.TXT OPCINS.TXT OPCMN$.TXT OPRMN$.TXT VII. Optional File: EMCONFIG.DAT-> SER 3F8 PAR 378 SER port address, PAR port address & TICK is count to yield 0.025 ms delay, necessary for signal timing. TICK - depends on the PC CPU speed. The value in the file is used as a starting value to detemine a final value, this makes startup faster. To find an initial value to put in the CONFIG file, rename the file to EMCONFIG.DDD and the value determined will be indicated at startup.
