FIFO Data.
A Write (R/W = 1) to this Address will begin a Burst Write to the TX FIFO. The FIFO will
be loaded in the same manner as a Burst SPI Write but the SPI address will not be incre-
mented. To conclude the TX FIFO Write the SEL pin should be brought HIGH. A Read
(R/W = 0) to this address will begin a burst read of the RX FIFO, in the same manner.
