Clamping
The clamping function is useful for separating the output range into an operating range
and error ranges. If the magnetic field is exceeding the selected measurement range, the
output value OUT is limited to the clamping values. Any value in the error range is
interpreted as an error by the sensor counterpart.

The clamping values are calculated by:
Clamping value low (deactivated if CL=0):
OUT_CL = CL ⋅ 32 ⋅ 16
Clamping value high (deactivated if CH=127):
OUT_CH = (CH + 1) ⋅ 32 ⋅ 16 – 1
