CLKI 39 63 F9 B34 I
ST/
CMOS
External clock source input. Always 
associated with OSC1 pin function.
CLKO 40 64 F11 A42 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 B34 I
ST/
CMOS
Oscillator crystal input. ST buffer when 
configured in RC mode; CMOS 
otherwise.
OSC2 40 64 F11 A42 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 A47 I
ST/
CMOS
32.768 kHz low-power oscillator crystal 
input; CMOS otherwise
SOSCO 48 74 B11 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
