7.1 Synchronous Serial Interface (SSI)

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.

Figure 4. Read / Write Serial Data Transmission

Figure 4 shows the connection of the AS5132 to a micro controller. Depending on the command byte are different access types possible. In

normal mode the number of clocks is equal the number of data bits.
