Master Clear (input) or programming voltage (input)
Oscillator crystal or external clock input
Oscillator crystal or clock output
Active-low Master Clear (device Reset) input
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/CLKIN,
OSC2/CLKOUT pins)
General purpose I/O pin
Oscillator crystal output. Connects 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
