Master clear (input) or programming voltage (input).
These pins should be left unconnected.
Oscillator crystal or external clock input.
Oscillator crystal output.
PORTA is a bi-directional I/O port.
Master Clear (Reset) input. This pin is an active
low RESET to the device.
Programming voltage 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 OSC1/CLKIN,
