4.13 DEBUGGING CODE USING NATIVE TRACE

The trace function can be used to collect information on variables and code and store

it in a buffer while the code is executing.

In this section, Native trace will be used. For more information about tracing in general

using the MPLAB REAL ICE in-circuit emulator, see Chapter 7. “Debug for 8- and

16-Bit Devices”.

4.13.1 Logging a Variable Value

To log a variable value:

1. Select Project>Build Options>Project, Trace tab. Check “Enable Trace” and

uncheck “Disable Trace Macros”. Then select the type of trace, i.e., “Native

Trace” for devices with built-in ICE support. Click OK.

Note 1: Trace operation requires 16-bit C compiler v2.04 and above.

2: Real-time data capture triggers (from the previous section) cannot be

used at the same time as Native trace.
