Transmit Data field.
Transmission: To be transmitted data field. SW
provides data field.
HW shadows over the write data to TX FIFO after SW
performs a write to this field.
HW shadows the whole 8 bits to the TX FIFO and
relies on the TXPID_FI.FI/TXPID_FI.DCLEXT to
determine the number of bytes.
SW needs to ensure that TX FIFO is not overwritten
before the content is consumed by HW by checking
TX_FIFO_STATUS.AVAIL. Otherwise, the previous
content would be overwritten and resulting in TX
FIFO's overflow error
(INTR.TX_OVERFLOW_ERROR).
