An independent sink remains on continuously when SCx_EN = 1 and SCx_OFF is 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, then when the independent current sink is enabled (Register 0x10) it
remains on for the on 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.
