Description

MCLR

MCLR

1 18 18

Master Clear (input) or programming voltage (input).

I

ST

Master Clear (Reset) input. This pin is an active-low

Reset to the device.

OSC1/CLKI

OSC1

CLKI

13 32 30

Oscillator crystal or external clock input.

I

—

Oscillator crystal input or external clock source input.

I CMOS External clock source input. Always associated with

pin function OSC1. See related OSC2/CLKO pins.

OSC2/CLKO

OSC2

14 33 31

O

O

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.

Legend: TTL = TTL compatible input

ST = Schmitt Trigger input with CMOS levels

O = Output

CMOS = CMOS compatible input or output

I

= Input

P

= Power

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

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