Note2: The protection circuit makes the backlight turn off, when tLPW is more than 50ms.
the duty value of input signal for BRTP.
Duty=40%: luminance is minimum.
Outside control is valid, when PWSEL="L" and input signal for BRTP. Luminance can be controlled by
Duty=100%: luminance is maximum.
Note1: Regarding set up for frequency, refer to the below method.
