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 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
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/CLKIN, OSC2/CLKOUT
pins)
