MON08 PORT
The MON08 port is a 16-pin header compatible with a Motorola MON08 Monitor Mode Pod.
This allows the connection of a background debugger for software development, programming,
and debugging in real-time without using HC08 I/O resources.
Figure 11: MON08 Port Connector
When using the MON08 pod to access monitor mode, care must be exercised to configure the
host software correctly. Many MON08 Pods are capable to powering the target board through
the MON08 Port. In this case, the appropriate voltages will be applied to the board and the
state of the monitor configuration jumpers is DON’T CARE. If the board is not powered
through the MON08 Port, then the minimum applied voltage is +9VDC and the VTST_EN
jumper must be installed. Regardless of how the board is powered, the state of the MON_EN
jumper is DON’T CARE. When using the MON08 Port for monitor access, the COM_MODE
jumper should be set to 2 – 3 to allow RS-232 communications.

USER Components
The DEMO908GZ60 provides 2 user push switches, 2 user LED indicators, a potentiometer,
and photocell circuit for user applications. USER_EN option jumper allows each option to be
enabled or disabled individually.
