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.

SC7 off time. When the SC off time is disabled, the SC remains on while enabled. When the SC off time is set to
any other value, the ISC turns off for the off time (per the following listed times) and then turns on according to
the SCON setting.
0000 = disabled
0000001 = 0.0 sec
0000010 = 0.1 sec.
0000011 = 0.2 sec.
