An independent sink remains on continuously when SCx_EN = 1 and SCxOFF = 00 (disabled).
To enable multiple independent sinks, set the appropriate SCx_EN bits. To create equivalent blinking and fading sequences, enable all independent sinks in one write
cycle to cause a preprogrammed sequence to start simultaneously.

Bit 6
Description
SC on time. If the SCxOFF time is not disabled and the independent current sink is enabled (Register 0x10), the LED(s)
remains on for the time selected (per the following list) and then turns off.
00 = 0.2 sec
01 = 0.6 sec
10 = 0.8 sec
11 = 1.2 sec
SC7 off time. When the SC off time is disabled, the ISC 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.
00 = off time disabled
01 = 0.6 sec
10 = 1.2 sec
11 = 1.8 sec
SC6 off time. When the SC off time is disabled, the ISC 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.
00 = off time disabled
01 = 0.6 sec
10 = 1.2 sec
11 = 1.8 sec
SC5 off time. When the SC off time is disabled, the ISC 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.
00 = off time disabled
01 = 0.6 sec
10 = 1.2 sec
11 = 1.8 sec
