7.3.3.3 MPLAB X IDE SETUP

To set up MPLAB X IDE to use trace for the MPLAB REAL ICE in-circuit emulator:

1. Right click on the project name and select “Properties”. In the Project Properties

dialog click on “Real ICE” under “Categories”.

2. Under “Option categories”, select “Clock”. For data capture and trace, the

emulator needs to know the instruction cycle speed.

3. Under “Option categories”, select “Trace and Profiling”.

4. Under “Data Collection Selection”, choose “Instruction Trace/Profiling”.

5. Set up any other trace-related options. (See Section 11.3.1 “Trace and

Profiling”.)

6. Click OK.

On a Debug Run, trace will continue to fill the trace buffer with data, rolling over when

the buffer is full, until a program Halt.

7.3.3.4 VIEWING TRACE DATA

When trace is enabled and code is run, trace data will be collected by the emulator.

Once the device is halted, trace data will be decoded and displayed in the Trace

window (Window>Debugging>Trace

7.3.4 Trace Hardware Specifications

Specifications for hardware that supports PIC32 Instruction Trace are listed below.

7.3.4.1 MPLAB REAL ICE TRACE INTERFACE KIT (AC244006)

The MPLAB REAL ICE Trace Interface Kit consists of an adapter board and trace

cable. Kit component dimensions and a pin connection diagram for the adapter board

are shown below.

Note: When using trace, pins TRCLK and TRD3:0 are used. Therefore, you

cannot use the other functions multiplexed on these pins. For

PIC32MX360F512L, multiplexed functions are RG14:12 and RA7:6.
