debugging features. The OCI provides run control, memory and register visibility,
complex break points, and trace history features.
The OCI employs all of the functions of the ZiLOG Debug Interface (ZDI) as
described in the ZDI section. It also adds the following debug features:
•
•
•
•
•
There are four sections to the OCI:
