When set, the FIFO is in transmit mode. When cleared, the FIFO is in receive mode.
When set, clears the FIFO by resetting the pointers to the empty position. This bit
must then be cleared to enable operation of the FIFO. Failing to do so, will
prohibit operation of the FIFO. The state of the bit can not be read.
When set, indicates there is no data in the FIFO.
