6.3 EXTERNAL TRIGGERS

Select Debugger>Triggers to open the Triggers dialog to set up external triggers. See

Section 11.3.7 “Triggers Dialog” for more information.

Use external triggers to set up hardware triggers using the logic probe port. All pins

(whether used or unused) should either be pulled up or grounded. Floating pins may

produce false triggers.

To use probe pins as inputs, you must provide the circuitry to drive them (see Table

12-2: “Logic Probe Electrical Specifications” for drive levels.)

You will not be able to use external triggers if you are using the logic probe port for

another debug feature such as:

• Section 7.3.3.2 “I/O Port Trace”

• Section 8.3 “PIC32 Instruction Trace”
