An independent sink remains on continuously when it is enabled and SCxOFF is 00 (disabled).
2
Setting SCxOFF to 0 seconds is not recommended if the SCFO fade-out time is also set to 0 seconds.
3
Setting SCxOFF to off causes the LED to be held off indefinitely. This is useful for setting up a blink sequence that runs once and then goes to off.
