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.
Pulse modulation/demodulation for infrared communication
Compatible to IrDA 1.4 physical for baud rates up to 115.2 kbps
Selectable pulse modulation scheme
Built in filtering
Can be connected to and used by one USART at a time
– 3/16 of baud rate period
– Fixed pulse period, 8-bit programmable
– Pulse modulation disabled
