DIP Pin

I/O/P

Type

I/O

Buffer

Type

TTL/ST

Description

Bi-directional I/O port/serial programming data/analog input

0. Can be software programmed for internal weak pull-up

and interrupt on pin change. This buffer is a Schmitt Trigger

input when used in serial programming mode.

Bi-directional I/O port/serial programming clock/analog

input 1/voltage reference. Can be software programmed for

internal weak pull-up and interrupt on pin change. This

buffer is a Schmitt Trigger input when used in serial pro-

gramming mode.

Bi-directional I/O port/analog input 2. Can be con铿乬ured as

T0CKI or external interrupt.

Input port/master clear (reset) input/programming voltage

input. When con铿乬ured as MCLR, this pin is an active low

reset to the device. Voltage on MCLR/V

must not exceed

during normal device operation. Can be software pro-

grammed for internal weak pull-up and interrupt on pin

change. Weak pull-up always on if con铿乬ured as MCLR .

This buffer is Schmitt Trigger when in MCLR mode.

Bi-directional I/O port/oscillator crystal output/analog input

3. Connections to crystal or resonator in crystal oscillator

mode (HS, XT and LP modes only, GPIO in other modes).

In EXTRC and INTRC modes, the pin output can be con铿乬-

ured to CLKOUT which has 1/4 the frequency of OSC1 and

denotes the instruction cycle rate.

Bidirectional IO port/oscillator crystal input/external clock

source input (GPIO in INTRC mode only, OSC1 in all other

oscillator modes). Schmitt trigger in EXTRC mode only.

Positive supply for logic and I/O pins

Ground reference for logic and I/O pins
