20.7.4 DATA – Data register
The DATA register is used for sending and receiving data. Writing to the register initiates the data transmission, and the
byte written to the register will be shifted out on the SPI output line. Reading the register causes the shift register receive
buffer to be read, returning the last byte successfully received.
