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 incremented. 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.
