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 SCxOFF = 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, 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, 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
