CCP2 is multiplexed with RC1 when Configuration bit, CCP2MX, is set, or RE7 when CCP2MX is not set.
RG5 is only available when MCLR functionality is disabled.
OSC1/CLKI and OSC2/CLKO are only available in select oscillator modes and when these pins are not being used as digital I/O.
For additional information, see Section 2.0 “Oscillator Configurations” of the “PIC18F6390/6490/8390/8490 Data Sheet” (DS39629).
