An independent sink remains on continuously when it is enabled and SCxOFF is 00 (disabled).
An independent sink remains on continuously when it is enabled and SCxOFF is 00 (disabled).
Setting SCxOFF to 0 seconds is not recommended if the SCFO fade-out time is also set to 0 seconds.
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.
