Figure 13-77 shows DMA transmission.
Figure 13-77 DMA TransmissionIn IrDA mode, the transmission does not end immediately after the TX FIFO empties, at which point the last data byte, the CRC field, and the stop flag still must be transmitted; thus, the end of transmission occurs a few milliseconds after the UART_THR register empties.
