• Code Coverage
• Trace Window
These features will each be discussed in the following sections. For more
detailed information on each of these features, please refer to Chapter 6.
Using Complex Triggering
MPLAB ICE has a highly flexible and powerful triggering mechanism. A trigger
is a combination of events that can cause:
• a hardware break point, and/or
• a trace memory capture.
An event is a description of the state of the system captured during one cycle.
In addition, an external signal can be generated when the trigger occurs. This
is useful for synchronizing other analyzers or equipment to MPLAB ICE.
