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.

Serial 2-Wire Differential SSI Connection
With the addition of a RS-422 / RS-485 transceiver, a fully differential data transmission, according to the 21-bit SSI
interface standard is possible. To be compatible with this standard, the DCLK signal must be inverted. This is done by
reversing the Data+ and Data- lines of the transceiver.
Note: This type of transmission is read-only.
