5.5.3.1 Native Trace

Native trace can be used with the information conveyed via the PGD/PGC or EMUC/EMUD pins. This two-wire interface uses the trace macro format (see Setting Up Trace in MPLAB X IDE). Either a 6- or 8-pin ICSP™ connection can be used for Native trace.

For 8-bit and 16-bit devices, Native trace requires that you enter the clock speed (Project Properties dialog, ICE4 category, Clock options category).

If Native trace is used, then data captures cannot be used as these features use the same device resource. Breakpoints are still available, but be aware that Native trace will use one breakpoint for tracing. This will NOT be reflected on the Device Debug Resource toolbar.

To use data capture triggers, you must disable Native trace (see Disabling Trace).
