Clamping

The clamping function is useful for splitting the output voltage range into operating range

and error ranges. If the magnetic field is outside the selected measurement range, the

output value

interpreted as an error by the sensor counterpart.

The clamping values are calculated by:

Clamping duty cycle low (deactivated if CL=0):

Clamping duty cycle high (deactivated if CH=127):
