CCB<15:8>: Command Code bits
The command code bits (10110000b) are serially sent to the microcontroller to identify the bits to be
written in the RXFIFOREG.
RXDB<7:0>: Receiver Data Byte bits
These are the recovered data bits stored in the FIFO. The controller can read 8 bits from the receiver
FIFO over the SPI bus. The FIFOEN bit (GENCREG<6>) should be set to receive these bits.
