CLKI 39 63 F9 I ST/CMOS External clock source input. Always associated
with OSC1 pin function.
CLKO 40 64 F11 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 39 63 F9 I ST/CMOS Oscillator crystal input. ST buffer when
configured in RC mode; CMOS otherwise.
OSC2 40 64 F11 I/O — Oscillator crystal output. Connects to crystal or
resonator in Crystal Oscillator mode. Optionally
functions as CLKO in RC and EC modes.
SOSCI 47 73 C10 I ST/CMOS 32.768 kHz low-power oscillator crystal input;
CMOS otherwise.
SOSCO 48 74 B11 O — 32.768 kHz low-power oscillator crystal output.
Legend: CMOS = CMOS compatible input or output Analog = Analog input P = Power
ST = Schmitt Trigger input with CMOS levels O = Output I = Input
TTL = TTL input buffer
