Description

OSC1/CLKIN

ST/CMOS(1) Oscillator crystal input/external clock source input.

OSC2/CLKOUT

—

Oscillator crystal output. Connects to crystal or resonator in crystal

oscillator mode. In RC mode, the pin outputs CLKOUT which has

1/4 the frequency of OSC1, and denotes the instruction cycle rate.

MCLR/VPP

I/P

Master clear reset input or programming voltage input. This pin is an

active low reset to the device.

PORTA is a bi-directional I/O port.

RA0

RA4/T0CKI

I/O

RA4 can also be the clock input to the Timer0 timer/counter.

Output is open drain type.

PORTB is a bi-directional I/O port. PORTB can be software pro-

grammed for internal weak pull-up on all inputs.

RB0/INT

I/O

TTL/ST(2)

RB0 can also be the external interrupt pin.

TTL

Interrupt on change pin.

RB5

I/O

TTL

Interrupt on change pin.

RB6

I/O

TTL/ST(3)

Interrupt on change pin. Serial programming clock.

RB7

I/O

TTL/ST(3)

Interrupt on change pin. Serial programming data.

VSS

—

Ground reference for logic and I/O pins.

VDD

—

Positive supply 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

Note 1:

This buffer is a Schmitt Trigger input when conﬁgured in RC oscillator mode and a CMOS input otherwise.

This buffer is a Schmitt Trigger input when conﬁgured as the external interrupt.

This buffer is a Schmitt Trigger input when used in serial programming mode.
