By connecting the configuration input C2 to VDD, the AS5030
is configured to 2-wire data transmission mode.
Only Clock (CLK) and Data (DIO) signals are required. A Chip
Select (CS) signal is automatically generated by the DX output,
when a time-out of CLK occurs (typ. 20µs).
Note: Read-only mode is also possible in this configuration
