I/O/P

Type

Buffer

Type

Description

RB0

I/O

TTL/ST Bi-directional I/O port/ serial programming data. Can

be software programmed for internal weak pull-up and

wake-up from SLEEP on pin change. This buffer is a

Schmitt Trigger input when used in serial programming

mode.

RB1

I/O

TTL/ST Bi-directional I/O port/ serial programming clock. Can

be software programmed for internal weak pull-up and

wake-up from SLEEP on pin change. This buffer is a

Schmitt Trigger input when used in serial programming

mode.

RB2

I/O

TTL

Bi-directional I/O port.

RC0

I/O

TTL

Bi-directional I/O port.

RC1

I/O

TTL

Bi-directional I/O port.

RC2

I/O

TTL

Bi-directional I/O port.

RC3

I/O

TTL

Bi-directional I/O port.

RC4

I/O

TTL

Bi-directional I/O port.

RC5/T0CKI

I/O

Bi-directional I/O port. Can be conﬁgured as T0CKI.

RB3/MCLR/VPP

TTL

Input port/master clear (reset) input/programming volt-

age input. When conﬁgured as MCLR, this pin is an

active low reset to the device. Voltage on MCLR/VPP

must not exceed VDD during normal device operation.

Can be software programmed for internal weak pull-up

and wake-up from SLEEP on pin change. Weak pull-

up only when conﬁgured as RB3.

RB4/OSC2/CLKOUT

I/O

TTL

Bi-directional I/O port/oscillator crystal output. Con-

nections to crystal or resonator in crystal oscillator

mode (XT and LP modes only, RB4 in other modes).

Can be software programmed for internal weak pull-up

and wake-up from SLEEP on pin change. In EXTRC

and INTRC modes, the pin output can be conﬁgured to

CLKOUT, which has 1/4 the frequency of OSC1 and

denotes the instruction cycle rate.

RB5/OSC1/CLKIN

I/O

TTL/ST Bidirectional IO port/oscillator crystal input/external

clock source input (RB5 in Internal RC mode only,

OSC1 in all other oscillator modes). TTL input when

RB5, ST input in external RC oscillator mode.

VDD

—

Positive supply for logic and I/O pins

VSS

—

Ground reference for logic and I/O pins

Legend: I = input, O = output, I/O = input/output, P = power, — = not used, TTL = TTL input,

ST = Schmitt Trigger input
