3 Operation

A simplified theory of operation of the MPLAB ICD 4 In-Circuit Debugger system is provided here. It is intended to provide enough information so that a target board can be designed that is compatible with the debugger for both debugging and programming operations. The basic theory of in-circuit debugging and programming is discussed so that problems, if encountered, are quickly resolved.
