Note 1:
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.
These pins are only available on 44-pin TQFP packages under certain conditions.
RB3 is the alternate pin for CCP2 multiplexing.
