Description
Lit when power is first applied or when target is connected.
Lit when the emulator is operating normally – standby.
Lit when an operation has failed.
Lit when the emulator is busy.
12.5.4
Logic Probe/External Trigger Interface
Probes can be connected to the 14-pin header on the side of the unit for processing
external signals that are used for triggering external equipment. This header contains
8 input/output connections that are user selectable as inputs or outputs with logic levels
that are proportional to the target operating voltage. The outputs can be used for
triggering an external logic analyzer or oscilloscope to allow the developer to capture
events of interest based on trigger criteria set within MPLAB IDE.
The inputs are part of a trigger bus.

Logic probes may be attached to this connector to give the functionality described in
Table 12-1. The probes are color coded and labeled for easy identification.
