Master Clear (input) or programming voltage (input).
Oscillator crystal or external clock input.
Oscillator crystal or clock output.
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.
External clock source input. Always associated with pin
function OSC1. (See OSC2/CLKO pin.)
Oscillator crystal output. Connects to crystal or resonator in
Crystal Oscillator mode.
In select modes, OSC2 pin outputs CLKO which has 1/4 the
frequency of OSC1 and denotes the instruction cycle rate.
General purpose I/O pin.
