The UART control registers support both the UARTs and the associated Infrared Encoder/
Decoders. For more information on the infrared operation, refer to the Infrared Encoder/
Decoder chapter on page 95.
Data bytes written to the UARTx Transmit Data register (Table 50) are shifted out on the
TXDx pin. The Write-only UARTx Transmit Data register shares a Register File address
with the Read-only UARTx Receive Data register.
