External clock source input. Always associated with
pin function OSC1 (See related OSC1/CLKIN,
OSC2/CLKOUT pins)
General purpose I/O pin
Oscillator crystal output. Connects to crystal
or resonator in Crystal Oscillator mode
In RC mode, OSC2 pin outputs CLKOUT which
has 1/4 the frequency of OSC1 and denotes
the instruction cycle rate
