description: |
|
Note that a driver will take the lowest of all LED limits |
|
since the chip has a single global setting. The lowest value |
|
will be chosen due to the PWM specificity, where lower |
|
brightness is achieved by reducing the duty-cycle of pulses |
|
and not the current, which will always have its peak value |
|
equal to led-max-microamp. |
