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