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;
CMOS otherwise.
External clock source input. Always associated with
pin function OSC1. (See related OSC2/CLKO pin.)
General purpose I/O pin.
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.
