I
ST Master Clear (Reset) input. This pin is an active-low Reset
to the device.
39
Oscillator crystal or external clock input.
I
ST
Oscillator crystal input or external clock source input.
ST buffer when configured in RC mode; CMOS
otherwise.
I CMOS External clock source input. Always associated
with pin function OSC1. (See related OSC1/CLKI,
OSC2/CLKO pins.)
40
Oscillator crystal or clock output.
O
—
Oscillator crystal output. Connects to crystal or
resonator in Crystal Oscillator mode.
O

In RC mode, OSC2 pin outputs CLKO which has
1/4 the frequency of OSC1 and denotes the
instruction cycle rate.
PORTA is a bidirectional I/O port.
