FL_I_FL1

R

These bits contain the flash current value for LED1 when the dc current limit fault occurs. The

current setting is equal to the value of these six bits multiplied by 12.5 mA (FL_I_FL1 × 12.5).

00 0000 = 0 mA.

00 0001 = 12.5 mA.

1

LED2_EN

R/W

This bit enables or disables the LED2 output.

0 = disable LED2 output (default).

1 = enable LED2 output.

To enable both channels at once, set both LED2_EN and LED1_EN to 0 and then set both bits to 1

to 1, this write is ignored.

0

LED1_EN

R/W

This bit enables or disables the LED1 output.

0 = disable LED1 output (default).

1 = enable LED1 output.

To enable both channels at once, set both LED1_EN and LED2_EN to 0 and then set both bits to 1

to 1, this write is ignored.
