Table 25. LED1 Flash Current Fault Readback Register (Register 0x0D)
Bits Bit Name Access Description
[7:6] Reserved R Reserved.
[5:0]
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.
…
00 1000 = 100 mA.
…
01 0100 = 250 mA.
…
10 1000 = 500 mA.
…
11 1100 = 750 mA.
Table 26. LED2 Flash Current Fault Readback Register (Register 0x0E)
Bits Bit Name Access Description
[7:6] Reserved R Reserved.
[5:0]
FL_I_FL2
R
These bits contain the flash current value for LED2 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_FL2 × 12.5).
00 0000 = 0 mA.
00 0001 = 12.5 mA.
…
00 1000 = 100 mA.
…
01 0100 = 250 mA.
…
10 1000 = 500 mA.
…
11 1100 = 750 mA.
Table 27. LED Enable Mode Register (Register 0x0F)
Bits Bit Name Access Description
[7:2] Reserved R/W Reserved.
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
in the same I
2
C write command. If LED1 is already enabled and the user tries to set the LED2_EN bit
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
in the same I
2
C write command. If LED2 is already enabled and the user tries to set the LED1_EN bit
to 1, this write is ignored.
