CLKI 31 49 B28 71 I ST/CMOS External clock source input. Always associated with
OSC1 pin function.
CLKO 32 50 A33 72 O — Oscillator crystal output. Connects to crystal or reso-
nator in Crystal Oscillator mode. Optionally functions
as CLKO in RC and EC modes. Always associated
with OSC2 pin function.
OSC1 31 49 B28 71 I ST/CMOS Oscillator crystal input. ST buffer when configured in
RC mode; CMOS otherwise.
OSC2 32 50 A33 72 O — Oscillator crystal output. Connects to crystal or reso-
nator in Crystal Oscillator mode. Optionally functions
as CLKO in RC and EC modes.
SOSCI 47 72 B41 105 I ST/CMOS 32.768 kHz low-power oscillator crystal input; CMOS
otherwise.
SOSCO 48 73 A49 106 O — 32.768 low-power oscillator crystal output.
