Description

General-Purpose I/O Ports A-H

PA[7:0]

I/O

Port A[7:0]. These pins are used for general-purpose I/O.

PB[7:0]

I/O

Port B[7:0]. These pins are used for general-purpose I/O.

PC[0]

I/O

Port C[0]. These pins are used for general-purpose I/O.

Pulse-Width Modulator for Motor Control

PWM0h/PWM1H

PWM2H

PWM High output.

PWM0L/PWM1L

PWM2L

PWM Low output.

FAULT0/FAULT1

PWM FAULT condition input. FAULT0 is active low, FAULT1 is active

high

SPI

MISO

I/O

Master In, Slave Out

MOSI

I/O

Master Out, Slave In.

SCLK

I/O

SPI Clock.

Slave Select

Timers

T0OUT, T0OUT

General-Purpose Timer Outputs.

T0INx

General-Purpose Timer Input. This signal is used as the capture, gating

and counter inputs.

UART Controller

TXD

Transmit Data. This signal is the transmit output from the UART and

IrDA.

RXD

Receive Data. This signal is the receiver input for the UART and IrDA.

CTS

Clear To Send signal from the receiving device that ready to receive

data.

TXDE

Driver Enable. This signal allows automatic control of external RS-485

drivers. The DE signal may be used to ensure an external RS-485 driver

is enabled when data is transmitted by the UART.
