5.5.3 Trace Methods
Currently there are three instrumented trace methods. All are language-tool-version dependent, and stream data in real time to MPLAB X IDE. The pluses and minuses of using each trace method, as well as communication information, are summarized below.
Trace Method | Speed | Code Size Impact | Real Time Op | Pin Usage | Device Feature Needed | High Speed Communication |
---|---|---|---|---|---|---|
Native Trace | Fast | Large | Close | None | Built-in debug | Greater than 15 MIPS1 |
SPI Trace | Faster | Medium | Closer | SPI pins | SPI | Yes1 |
I/O Port Trace | Fastest | Small | Closest | 9 pins of Debug Connector | None | Yes2 |
