Datasheet - Detailed Description
7.1.2 Extended Synchronous Serial Interface Mode
The absolute angle data can be read out over the synchronous serial interface using the pins CSN, DIO and CLK. It is a bidirectional interface
therefore a read or write access is possible. The organization of the protocol is byte wise and starts with the command byte followed by the data
information.
