Figure 8 shows an example in which the magnetic field range between B_min and B_max
is mapped to duty cycles between 16% and 84%.

Figure 8 Clamping example
Note: The clamping high value must be above the low value.
If CY_CLPWM is set to a higher value than CY_CHPWM, the CY_CHPWM value is
dominating. This would lead to a constant output duty cycle independent of the
magnetic field strength.
