Before downloading a memory image to the MPLAB PICkit 4 for PTG operation, the PICkit 4 programmer options should be set up for Programmer-To-Go operation. In fact, it is highly recommended to test programming a target device from the software first, with all desired options, to ensure the device programs as expected before downloading an image to Programmer-To-Go. Then you can put the PICkit 4 into PTG mode. Refer to the following sections for instructions.
