to run, stop and single-step through programs. One or more breakpoints can be set and
the processor can be reset. Once the processor is stopped, the contents of the register
can be examined and modified.

Due to the built-in in-circuit debugging capability of ICD devices and the ICSP function
offered by the debugger, the PICkit 3 Debug Express uses some on-chip resources
when debugging.
For a complete list of resources used by the debugger for your device, please see
MPLAB X IDE Start Page, click on Release Notes and Support Documentation, then
click on link for the Reserved Resources for PICkit 3.
