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.
