Polling Mode
Target of this mode is a reduction of the average power consumption. In this mode, the IC supply is pulsed, thereby
reducing the average power consumption to a fraction. The actual angle information and multi turn count value is not
lost; polling mode is especially suited for battery powered applications. The IC is furthermore capable of generating a
WAKE signal as soon as the magnet’s position has changed, but only if the supply of the IC is powered-on again. By
means of the WAKE signal, the system’s power consumption can be further decreased, if certain modules are
activated on demand.
