HARDWARE CONFIGURATION
The hardware configuration depends on the desired output: two-wire interface or analog.
In two-wire interface configuration, the slave address of the system can be configured by connecting A0 and
another pin as described in following table.

Table 15: TWI / I²C Slave address configuration
In analog mode, the rotation direction can be configured by connecting DVCC_SE and a power supply pin.
The user zero reference angle calibration can be activated by connecting A0 and COILP. When the user
zero reference angle calibration is active, the next evaluated magnetic angle will be set as the new zero
reference angle. The user selectable output voltage for the zero reference angle can be configured by
connecting A0 in series with a 4,7k ohm resistor and a port pin. The percentage indicated is relative to the
power supply value Vcc and is defined at the zero reference angle position.
