The following are the reference designs for LCM interfaces.
LCM can use external backlight drive circuit according to customer requirement. The reference design of
the external backlight drive circuit is shown in the figure below, in which pins PWM (PIN152&PIN238) can
be used for backlight brightness adjustment.
