For sending or receiving data, the master has to control the communication. The
command byte defines the region, address and type of command, which is requested by
the master, that is either a read or a write command. In case of a read command, an
additional handover or takeover bit respectively has to be inserted before and after the two
data bytes (see
Most Significant Byte (MSB) must be sent at first.
