Note: When enabling or disabling individual Hall elements to the SIN- and COS- signal buses it is recommended to allow
several milliseconds (typ. 5ms) of dwelling time until the signal is stable and eventual offsets are compensated.
11.3 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.
Table 16 Hall Sensor Front-End Default Configuration
The following configuration example selects Hall Sensor 0 and assigns it to the SIN signal bus:
Table 17 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:

always set to 0
set to 1 for enabled Hall Elements, set to 0 for disabled Hall Elements
set to 0 for disabled Hall Elements, set to 1 if this Hall Element should be added to the COS signal
bus. It is also possible to enable multiple Hall sensors to this bus
set to 0 for disabled Hall Elements, set to 1 if this Hall Element should be added to the SIN signal
bus. It is also possible to enable multiple Hall sensors to this bus
set to 1 if the Hall Element should be inverted for differential measurement. Set to 0 if the Hall
Element should not be inverted
set to 0 for normal operation, set to 1 if the Hall Sensor should be powered down.
