22. IRCOM - IR Communication Module

22.1 Features

22.2 Overview

• Pulse modulation/demodulation for infrared communication

• Compatible to IrDA 1.4 physical for baud rates up to 115.2 kbps

• Selectable pulse modulation scheme

– 3/16 of baud rate period

– Fixed pulse period, 8-bit programmable

– Pulse modulation disabled

• Built in filtering

• Can be connected to and used by one USART at a time

XMEGA contains an Infrared Communication Module (IRCOM) for IrDA communication with

baud rates up to 115.2 kbps. This supports three modulation schemes: 3/16 of baud rate period,

fixed programmable pulse time based on the Peripheral Clock speed, or pulse modulation dis-

abled. There is one IRCOM available which can be connected to any USART to enable infrared

pulse coding/decoding for that USART.
