Master Clear (input) or
programming voltage (output).
These pins should be left
unconnected.
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.
Oscillator crystal input or
external clock source input. ST
buffer when configured in RC
mode; otherwise, CMOS.
External clock source input.
Always associated with pin
function OSC1 (see OSC1/
CLKI, OSC2/CLKO pins).
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.
