FIFO is almost full. When the FIFO is empty it will automatically return to the
Idle State.

TX FIFO Reset/Clear.
This has to be a two writes operation: Setting ffclrtx =1 followed by ffclrtx = 0
will clear the contents of the TX FIFO.
Additional capacitance to course shift the frequency if xlc[6:0] is not sufficient.
Not binary
with xlc[6:0].
