Low-Cost Programming and Debugging Options for M68HC08 MCUs 5
MON08 Pods
The hardware that connects a PC and the target board ranges from
full-featured development tools to simple communications circuits that anyone
can build.
The ICS MON08
Connector
Motorola builds In-Circuit Simulators (ICS) for many popular M68HC08
derivatives. This tool provides a fairly sophisticated debug environment for
code developers and the capability to program individual MCU devices while
designing an application. The ICS contains a 16-pin ribbon cable that can mate
with a connector on the target board. This connector, typically called the
MON08 connector, is usually a 2-row by 8-pin (2 x 8) dual row header with
0.10 inch spacing. One end of the ribbon cable is attached to the ICS and the
other end is attached to the target application. The connector pinout is
described in the in-circuit simulator (ICS) kit for each particular M68HC08
MCU, and can also be found in most M68HC08 development tool
documentation. Figure 1 is an example of the MON08 connector pinout found
on the ICS tool for the MC68HC908GP32.
