RE3 is multiplexed with MCLR and is only available when the MCLR Resets are 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. Refer
to Section 2.0 “Oscillator Configurations” for additional information.
RB3 is the alternate pin for CCP2 multiplexing.
