AC162052 is a MPLAB ICD 14 pin header interface is required for debugging PIC16F676/630. The header interface provides In-Circuit Debugging capability to the 14 pin device. The header interface is connected in place of the target device and houses a standard MPLAB ICD 2 connector. In-circuit debugging is done via an MPLAB ICD 2. Once the code is debugged, the debugged software can then be programmed into the device and installed in the board replacing the header.
