Data Receive Register

The Data Receive Registers hold the value of received data of the last
executed transfer. Valid bits depend on the transmit bit length field in the
CNTRL register. For example, if CNTRL[Tx_BIT_LEN] is set to 0x08 and
CNTRL[Tx_NUM] is set to 0x0, bit Rx0[7:0] holds the received data.

NOTE: The Data Receive Registers are read only registers. A Write to
these registers will actually modify the Data Transmit Registers because
those registers share the same FFs.
