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
An independent sink remains on continuously when SCx_EN = 1 and SCx_OFF is 00 (disabled).

Description
SC4 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, then 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.
SC3 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, then 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.
SC2 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, then 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.
SC1 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, then 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.
