3.2.18 PWMs and LED Current Driver Interface
The SOM support dual PWM output and dual LED Current Driver, all PWM output by Light Pulse Generators.
LED Current Driver PINs can be used for different events, they are separate controller. Independently
programmable duty cycle and period via LPGs (6-or 9-bit resolution) for digital dimming.
Flash or blinking with register-selectable durations of ON-time from 0 to 1 second, in ≤ 0.05-second steps,
