5.5.3.3 I/O Port Trace

I/O Port trace can be used with either standard or high-speed communications. Trace clock and data are provided from a device 8-pin I/O port through the emulator’s logic probe connector.

The I/O port must have all 8 pins available for trace. The port must not be multiplexed with the currently-used PGC and PGD pins. Therefore, review the data sheet of the selected device to determine the uninitialized/default port pin states and change them as necessary.

For hardware connections, see IO Port Trace Connections.

The port interface uses the trace macro format (see Setting Up Trace in MPLAB X IDE).
