XMEGA contains an Infrared Communication Module (IRCOM) IrDA 1.4 compatible module for
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, and this can be connected to any USART to enable
infrared pulse coding/decoding for that USART.
