CLKI 39 63 B34 I ST/CMOS
External clock source input. Always associated with
OSC1 pin function.
CLKO 40 64 A42 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 the OSC2 pin function.
OSC1 39 63 B34 I ST/CMOS
Oscillator crystal input. ST buffer when configured in
RC mode; CMOS otherwise.
OSC2 40 64 A42 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 73 A47 I ST/CMOS
32.768 kHz low-power oscillator crystal input; CMOS
otherwise.
SOSCO 48 74 B40 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
