1: Optional multiplexing of CCP2 input/output with RB3 is enabled by selection of the CCP2MX configuration bit.
2: RE3 is available only when the MCLR Resets are disabled.
3: OSC1, OSC2, CLKI and CLKO are only available in select oscillator modes and when these pins are not being used as digital I/O.
Refer to Section 2.0 “Oscillator Configurations” for additional information.
