13 / 33 page ![]() AS5046 Programmable 360° Magnetic Angle Encoder – Preliminary Data Sheet Revision 1.1 www.austriamicrosystems.com Page 13 of 33 9.3 Hall Sensor Front-End Configuration 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.
