Features
Overview

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.
Figure 19-1. IRCOM connection to USARTs and associated port pins
The IRCOM is automatically enabled when a USART is set in IRCOM mode. When this is done
signals between the USART and the RX/TX pins are routed through the module as shown in
ure 19-1 on page
input for the IRCOM receiver. This will disable the RX input from the USART pin.
