XMEGA D4
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
â 3/16 of baud rate period
â Fixed pulse period, 8-bit programmable
â 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.
