otherwise CMOS. Main oscillator input
Oscillator crystal or external clock 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 or clock output
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.
