68HC11 Schematic in Bootstrap-Mode

A simple schematic for 68HC11 or 68HC811 in Bootstrap-Mode
MODA and MODB = 0 Volt
The RS232-circuit has a automatic RESET-circuit
My assembler ASY.EXE send a BREAK-Signal with 110 Baud
and this signal charge the condenser C5
BOOTSTRAP continue ...

ASSEMBLER / DISASSEMBLER 68HC11
assem.zip (38.925 Bytes)

Explode : ASY.EXE fast assembler for 68hc11 with automatic download.
Usage: ASY.EXE TEST.ASS [ENTER]
With the extension "ASS" the assembler loads automatically in the
internal EEPROM (B600-B7FF) of 68HC11

DISASSEMBLER FOR 68HC11
dishc11.zip (44.932 Bytes)
Explode : MAKEASS.EXE and DISASS.EXE
The programm MAKEASS.EXE convert a BINFILE in a Source-Textfile
with lines like the follow:
FCB $86,$01,$B7,$10,$3D,8E,$00,$FF $E000-$E007

Any assembler convert this Source-Textfile in a Binfile to compare
with the original BINFILE.

The disassembler DISASS.EXE opens the original BINFILE and the user
can see the binary and disassembled code.
With F8 the user can save a marked block and
insert in the Source-Textfile created with MAKEASS.EXE.
Step by step the user can disassembled all the routines of the
orginal BINFILE.
The user must decide if the code is a program, a text or a datatable.
The reassambled code with a compare (FC file compare) is the security.

SET CONFIG-REGISTER of 68HC11,68HC811

SETCONF.ZIP (25.784 Bytes)
Usage: SETCONF.EXE 09 [ENTER]
The CONFIG-REGISTER is set to hexvalue 09
The board with 68HC11 must be in BOOTSTRAP-MODE
