Function
Transmit FIFO Clear:
Set this bit to flush the entire transmit FIFO. All flags in TXFLG revert to
their reset states (TXEMP is set; all other flags clear) and all the
read/write pointers and makers are reset. The TXISO bit in this register
and the TXSEQ bit in the TXSTAL register are not affected by this
operation. Hardware clears this bit when the flush operation is
completed.

The value read from this bit is indeterminate. Write zero to this bit.
