otherwise CMOS. Main oscillator input
Oscillator crystal input or external clock source
input. ST buffer when configured in RC mode;
connection.
External clock source input; always associated
with pin function, OSC1 (see related OSC1/CLKI
pins).
Digital I/O.
Oscillator crystal output. Connects to crystal or
resonator in Crystal Oscillator mode.
Main oscillator feedback output connection
in RC mode, OSC2 pin outputs CLKO, which
has 1/4 the frequency of OSC1 and denotes
the instruction cycle rate.
