Master Clear (Reset) input. This pin is an active-low
Reset to the device.
Programming voltage input.
Digital input.
Oscillator crystal input or external clock source input.
ST buffer when configured in RC mode;
analog otherwise.
External clock source input. Always associated with
pin function OSC1. (See related OSC1/CLKI,
OSC2/CLKO pins.)
General purpose I/O pin.
Oscillator crystal output. Connects to crystal
or resonator in Crystal Oscillator mode.
In RC, EC and INTIO modes, OSC2 pin outputs
CLKO which has one-fourth the frequency of OSC1
and denotes the instruction cycle rate.
General purpose I/O pin.
