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.
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
