MON08 Interface is a debug interface
that allows a PC to interface to a Freescale HC08 microcontroller's
monitor debug mode. It connects between the serial port on your PC
and the standard 16-pin debug connector on your target.
The MON08 Interface lets the user take
advantage of the monitor mode to control the processor. The user can
directly control the targets execution, read/write registers and memory
values, debug code on the processor, and program internal or external
FLASH memory devices. This hardware device requires software on
the Users PC to operate. This software is available from
I developed this board after a few years
of working with the HC908 series parts. I finally worked out all the
bugs and it is working great. I have tested it with the GP, JL and KX
series processors. I am working on the GT series now. This device has a
lot of the good features for the MON08 interface. It allows you to break
a running program, it has an onboard Crystal to give you communication
speeds of 9600 or 19200 baud and automatically controls the Power to your target
so you don't have to manually turn on and off your target. It only
operates on 5V targets right now.
