M11 is mainly intended for programming and testing the single board computers ZWERG11A, ZWERG11plus and IC11B. However, M11 is also able to access other HC11-based boards, provided the processor runs at 2MHz, and the target has a serial interface, which can be connected to a serial port of the PC. In addition the HC11 should be resettable in "Special Bootstrap Mode" via DTR (For the ZWERG connect DTR to Reset).

M11 is available for Linux and DOS (also Windows9x DOS box).

M11 may be used interactively (including history and commandline editing/completion), execute commands from the command line or from script files. Settings may be stored in an init file.

Commands:

dump	Display memory area (hex/ASCII)
edit	Edit memory area (hex/ASCII)
memory	Read/write memory location/HC11-register/
config	Read/write config register/
Program	Load binary/S-Record file
Verify	Verify binary/S-Record file
Dump	Write memory area binary to file
Compare	Compare memory area to byte
fill	Fill memory area with byte
test	Test memory area
internal	Define internal EEPROM
xtern	Define external EEPROM (ZWERG+)
protect	Turn on/off write protection for external EEPROM
bus	Turn on/off bus mode
Spi	Send and receive byte via SPI
Rtc	Read/set RTC (ZWERG, ZWERG+, IC11B)
goto	Start program
reset	Reset, "boot" file

M11 identifies - if possible - the target automatically at reset (type of processor, internal EEPROM, PRU), and knows the symbolic names of the HC11-registers.

When downloading to the ZWERG11A, ZWERG11plus and IC11B, M11 uses the appropriate write algorithm according to the memory type (RAM, int. EEPROM, ext. EEPROM) at the address to write to.

The ICC11 C-compiler from  ImageCraft is recommended for program development (requires at least HC11-E2, or external RAM/EEPROM). This compiler generates S-record files, which M11 can download/program directly. Because ICC11 also provides a make utility, this procedure may comfortably be included in a makefile.
