In addition to debugger functions, the PICkit 3 programmer/debugger system also may be used as a development programmer. The debugger system executes code like an actual device because it uses a device with built-in emulation circuitry, instead of a special debugger chip, for emulation.

  • Page 23 ) and 3 (V ) are shown on Figure 2-4 for completeness. PICkit 3 has two configurations for powering the target device: internal debugger and external target power. The recommended source of power is external and derived from the target application.
  • Page 24 The first requires that an application be programmed into the target device (usually with the PICkit 3 itself). The second uses the internal in-circuit debug hardware of the target Flash device to run and test the application program. These two steps are directly related to the MPLAB IDE operations: 1.
