Vp-p MAX (LOCTEST) The maximum peak-to-peak voltage for the LOCTEST signal. The amplitude of the signal
will depend on the total stack-up TIR of the code wheel.

The average value of Duty % is then calculated based on the number of valid TILTOUT
pulses captured.
ON Pulse Width The ON pulse width of the TiltOut signal, t.
Pulse Ratio The ratio of periods between pulses generated at TiltOut.
