(1) Set sub-address (00) 70 and (02) 82.
(2) Input signal b ((horizontal 31.5 kHz ) to pin 11 (HD3-IN).
(3) Decreasing the duty of signal b to 0% (get negative period shorter), measure the duty of Signal b
(4) Increasing the duty of Signal b to 100% (get negative period longer), measure the duty of Signal b
(HD-DUTY1) when the phase between pin 11 and pin 13 (HD1-OUT) change.
