Depending on your selected device, one or more trace capabilities may be available when the emulator is selected as the debug tool. To determine trace support, see Hardware Tool Debug Feature Support by Device.
Native Trace Connections
No additional connections are necessary to use Native trace. The communications connection will carry the trace information using the PGD/PGC/EMUC/EMUD pins. However, the selected device must have this feature. If it does not, one of the other trace methods may be used.
For more on this type of trace, see Types of Instrumented Trace.
SPI Trace Connections (High-Speed/LVDS Connection)
Serial trace is an optional trace that is only available by using the Performance Pak (AC244002). For details, see the Performance Pak for the MPLAB® REAL ICE™ In-Circuit Emulator User’s Guide (DS50002528).
For more on this type of trace, see Types of Instrumented Trace.
I/O Port Trace Connections (Logic Port)
Parallel trace is possible using a device 8-pin I/O port and the emulator logic probes. This provides greater trace speed and data quantity, but limits emulator-to-target distance by the length of the logic probes.
For more on this type of trace, see Types of Instrumented Trace.
Instruction Trace Connections (Logic Port)
Instruction trace is a non-intrusive hardware trace used to capture every instruction executed by the device. There are two types of Instruction Trace: PIC32 Instruction Trace and Real Time Hardware Instruction Trace.
For more on these types of trace, see Instruction Trace.
