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
SPI_CNTRL register. For example, if TX_BIT_LEN is set to 0x08 and TX_NUM
is set to 0x0, bit RX0[7:0] holds the received data.
NOTE: The Data Receive Registers are read only registers.
