I

CMOS

Oscillator crystal input or external

clock source input. ST buffer when

configured in RC mode. Otherwise

CMOS.

External clock source input. Always

associated with pin function OSC1

(see OSC1/CLKI, OSC2/CLKO pins).

TTL

Oscillator crystal output.

Connects to crystal or resonator in

Crystal Oscillator mode.

In RC mode, OSC2 pin outputs CLKO,

which has 1/4 the frequency of OSC1

and denotes the instruction cycle rate

General purpose I/O pin

CMOS = CMOS compatible input or output

Analog = Analog input

O

= Output

OD = Open Drain (no P diode to VDD)
