DATA
1) The SO pin shows this information between CS hi -> lo and first SCLK lo -> hi transition.
Note: Reading a register needs two SPI frames. In the first frame the RD command is sent. In the second frame
the output at SPI signal SO will contain the requested information. A new command can be executed in the
second frame. The standard diagnosis can be accessed either by sending the standard diagnosis read
command or it is transmitted after each write command.
