3.1.1 Standard ICSP Device Communication
Attention: The MPLAB ICD 4 does not
support debug headers.
The debugger system can be configured to use standard 6-pin ICSP (modular cable) communication connection for both programming and debugging functions. The modular cable can be inserted a matching socket at the target, where the target device is on the target board (see figure below).
