Serial 3-Wire Connection (OTP Programming Option)
This mode provides with an option to configure the serial interface for programming the OTP register. Using a clock
input (CLK), DIO (Data) in/output and CS pin, it is possible to write and read out data from the OTP Register. The data
transfer is done via the DIO channel. For programming, the PROG pin must be connected to +8V. Analog readout for
trimming verification is mandatory.

1-Wire PWM Connection
If the line (PWM) is used as angle output, the total number of connections can be reduced to three, including the
supply lines. This type of configuration is especially useful for remote sensors. Low power mode is not possible in this
configuration. If the AS5130 angular data is invalid, the PWM output will remain at low state.
