Bit Name Bit No. Description
D2OFFINT 1 Include Diode 2 in the ISCOFF_INT flag.
1 = Diode 2 is in the group that triggers an ISCOFF_INT. When Diode 2 and all other LEDs with
DxOFFINT are set high and goes from on to off, ISCOFF_INT is set.
0 = Diode 2 is not in the group that triggers an ISCOFF_INT when all diodes in that group are off.
D1OFFINT 0 Include Diode 1 in the ISCOFF_INT flag.
1 = Diode 1 is in the group that triggers an ISCOFF_INT. When Diode 1 and all other LEDs with
DxOFFINT are set high and goes from on to off, ISCOFF_INT is set.
0 = Diode 1 is not in the group that triggers an ISCOFF_INT when all diodes in that group are off.

Description
N/A 7:3 Reserved.
1.5X_LIMIT 2 1 = gain is allowed to transition up from 1× to 1.5×. The gain is never allowed to enter 2× mode.
0 = gain is allowed to transition up from 1× to 1.5× to 2× as needed.
G_FORCE [1:0] Selects desired gain state.
00 = auto gain select.
01 = gain is locked into 1× mode.
10 = gain is locked into 1.5× mode.
11 = gain is locked into 2× mode (if 1.5X_LIMIT = 1, gain is locked into 1.5×)

D9LVL 6 Diode 9 level select.
1 = control with the LEVEL_SET bits.
0 = normal mode (25 mA full-scale current).
LEVEL_SET [5:0] Output level selection. Sets the mode of operation for all DxLVL bits that are set high.

111111 1.0 PWM current. In this mode, the INT pin functions as a PWM input and directly drives
the selected outputs.
