Standard and PWM-driven backlight
We have allowed LCD backlight to be enabled in two different ways:
1. It can be turned on with full brightness using SW4.1 switch.
2. Brightness level can be determined with PWM signal from the

In order to use PWM backlight both SW4.1 and SW4.3 switches must be
enabled at the same time.
