transceiver is passed to the Infrared Endec through the RXD pin, decoded by the Infrared
Endec and passed to the UART. Communication is half-duplex, that is, simultaneous data
transmission and reception is not allowed.
The baud rate is set by the UART’s Baud Rate Generator and supports IrDA standard baud
rates from 9600 baud to 115.2 Kbaud. Higher baud rates are possible, but do not meet
IrDA specifications. The UART must be enabled to use the Infrared Endec. The Infrared
Endec data rate is calculated using the following equation:
The data to be transmitted using the infrared transceiver is first sent to the UART. The
