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. For additional information, see Section 2.0 “Oscillator Configurations” of the

“PIC18F2420/2520/4420/4520 Data Sheet” (DS39631).
