Oscillator crystal or clock output.
Oscillator crystal output. Connects to crystal or resonator in
Crystal Oscillator mode.
In certain oscillator modes, OSC2 pin outputs CLKO,
which has 1/4 the frequency of OSC1 and denotes the
instruction cycle rate.
Remappable Peripheral Pin 6 input/output.
General purpose I/O pin.
Legend: TTL = TTL compatible input CMOS = CMOS compatible input or output
ST = Schmitt Trigger input with CMOS levels Analog = Analog input
I = Input O = Output
P = Power OD = Open-Drain (no P diode to V
