XMEGA A3B
23. IRCOM - IR Communication Module
23.1 Features
23.2 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 A3B 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 modula-
tion disabled. There is one IRCOM available which can be connected to any USART to enable
infrared pulse coding/decoding for that USART.
