ADC channel 3
Oscillator crystal output. Connect 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
Digital I/O
Oscillator crystal input or external clock input
ST buffer when configured in RC mode; analog other
wise
External clock source input. Always associated with the
pin function OSC1 (See related OSC1/CLKIN, OSC2,
