Serial 2-Wire Connection (R/W Mode)
By connecting the configuration input C2 to VDD, the AS5134 is configured to 2-wire data transmission mode. Only
Clock (DCLK) and Data (DIO) signals are required. A Chip Select (CS) signal is automatically generated by the DX
output, when a time-out of DCLK occurs (typ. 20µs).
Note: Read-only mode is also possible in this configuration.
