Description1, 2

SC4OFF

[7:6]

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

SC3OFF

[5:4]

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

11 = 1.8 sec

SC2OFF

[3:2]

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, 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

SC1OFF

[1:0]

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, 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

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

2 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. This causes a preprogrammed sequence to start simultaneously.
