AS5046 Programmable 360° Magnetic Angle Encoder – Preliminary Data Sheet
9.3
The default configuration for the Hall Sensor Front-End is set for angle measurement. This configuration must always be
programmed when an angle should be measured and read from the Serial Interface Unit register.
Table 4: Hall Sensor Front-End default configuration
The following configuration example selects Hall Sensor 0 and assigns it to the SIN signal bus:
Table 5: Example: Readout of a single Hall Sensor (Sensor #0)
This example uses two opposite Hall sensors 1 and 5 in differential mode and assigns the resulting signal to the COS signal
bus:
