SPI Data
The DATA register is used for sending and receiving data. Writing to the register initiates the data transmission when in Host mode while preparing data for sending in Client mode. The byte written to the register shifts out on the SPI output line when a transaction is initiated.
The SPIn.DATA register is not a physical register. Depending on what mode is configured, it is mapped to other registers, as described below.
