2.3.2 Setting Up and Using Trace
Trace requires hardware and software setup:
2.3.2.1 HARDWARE SETUP
To use trace, you will need the ribbon cable and emulator interface board that comes
with the emulation header. Connect one end to the emulation header (Figure 2-1). Con-
nect the other end to the emulator. For more information on complete hardware setup
and connections, refer to Section 1.4 “General Emulation Header Setup”.

2.3.2.2 MPLAB X IDE SETUP
To set up MPLAB X IDE to use trace for the MPLAB REAL ICE in-circuit emulator,
perform the following steps:
1. Right click on the project name and select “Properties” to open the Project
Properties window.
2. Click on “Real ICE” under “Categories”.
3. Under “Option categories”, select “Clock”.
For data capture and trace, the emulator needs to know the instruction cycle
speed.
4. Under “Option categories”, select “Trace and Profiling”.
5. Under “Data Collection Selection”, choose “Instruction Trace/Profiling”.
6. Set up any other trace-related options.
7. 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.
