This enable acts upon LED4.

1 = SC4 is turned on.

0 = SC4 is turned off.

SC3_EN

This enable acts upon LED3.

1 = SC3 is turned on.

0 = SC3 is turned off.

SC2_EN

This enable acts upon LED2.

1 = SC2 is turned on.

0 = SC2 is turned off.

SC1_EN

This enable acts upon LED1.

1 = SC1 is turned on.

0 = SC1 is turned off.

Description1, 2

SCON

[7:6]

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

SC7OFF

[5:4]

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

SC6OFF

[3:2]

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

SC5OFF

[1:0]

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

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 to cause a preprogrammed sequence to start simultaneously.
