CLKI 6 9 7 30 I ST/CMOS External clock source input. Always
associated with OSC1 pin function.
CLKO 7 10 8 31 O — Oscillator crystal output. Connects to
crystal or resonator in Crystal Oscillator
mode. Optionally functions as CLKO in
RC and EC modes. Always associated
with OSC2 pin function.
OSC1 6 9 7 30 I ST/CMOS Oscillator crystal input. ST buffer when
configured in RC mode; CMOS
otherwise.
OSC2 7 10 8 31 I/O — Oscillator crystal output. Connects to
crystal or resonator in Crystal Oscillator
mode. Optionally functions as CLKO in
RC and EC modes.
SOSCI 8 11 9 33 I ST/CMOS 32.768 kHz low-power oscillator crystal
input; CMOS otherwise.
SOSCO 9 12 10 34 O — 32.768 kHz low-power oscillator crystal
output.
