debugging using the PIC16F87X. 2.2 Highlights Topics covered in this chapter are: •  Enabling/Disabling the On-Chip Debugger •  Using the On-Chip Debugger Registers •  Communicating with the Target Device •  Resetting and Running Programs •  Halting Execution •  Additional Considerations 2.3 Enabling/Disabling the On-Chip Debugger The configuration bit BKBUG (bit 11 in the configuration word) is used to
enable/disable the on-chip debugger (Figure 2.1). See the programming specifications for PIC16C87X devices (DS39025) for
more information on programming the configuration word.
