... Module: Oscillator In-Circuit Serial Programming become unpredictable when a free-running clock source is present on OSC1. When entering ICSP mode, the PIC18C452 switches from OSC1 to RB6 for its external clock source. Refer to the PIC18CXXX Programming Specification (DS39028) for additional information. If OSC1 is high at the time, a high-to-low transition occurs upon the transition to RB6 ...
