Oscillator crystal or external clock input.

Oscillator crystal input or external clock source input.

ST buffer when configured in RC mode; CMOS otherwise.

External clock source input. Always associated with pin

function OSC1. (See related OSC1/CLKI, OSC2/CLKO

pins.)

General purpose I/O pin.

Oscillator crystal or clock output.

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.

Legend: TTL = TTL compatible input

CMOS = CMOS compatible input or output

ST = Schmitt Trigger input with CMOS levels I

Note 1: Default assignment for CCP2 when Configuration bit, CCP2MX, is set.

2: Alternate assignment for CCP2 when Configuration bit, CCP2MX, is cleared.
