It is recommended to connect the bottom pad of QFN package parts to VSS.
RB3 is the alternate pin for CCP2 multiplexing.
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.
