The clamping function is useful to split the output voltage range into operating range and
error ranges.
If the magnetic field is outside the selected measurement range, the output voltage
is limited to the clamping values.
Therefore an output voltage in the error range indicates a wire breakage (see
Circuit (OBD
The clamping function is enabled, when the clamp bit is set.

The following figure shows how the magnetic field range between
mapped to voltages between 0.5 V and 4.5 V.
If it is not necessary to signal errors, the clamping should be disabled. In this case the
maximum output voltage range between 0.3 V and 4.7 V can be used.
