    According to description about "Transmit Data Level",

    This bit field controls the level at which a DMA request
    is made by the transmit logic.

    It is equal to the watermark level.

    That is, the dma_tx_req signal is generated when the number
    of valid data entries in the TXFIFO
    (TXFIFO0 if CSR=00
    TXFIFO1 if CSR=01
    TXFIFO2 if CSR=10
    TXFIFO3 if CSR=11)
    is equal to or below this field value.

    Different to receive data level, transmit data level does not need
    to "-1".
