| STEP_UP | 7:6 | R/W | Adaptive headroom UP step size
00 = 105 mV 01 = 210 mV 10 = 420 mV 11 = 840 mV |
||||
| STEP_DN | 5:4 | R/W | Adaptive headroom DOWN step size
00 = 105 mV 01 = 210 mV 10 = 420 mV 11 = 840 mV |
||||
| LED_FAULT_TH | 3:2 | R/W | LED headroom fault threshold. This sets the HIGH comparator threshold.
00 = 5 V 01 = 4 V 10 = 3 V 11 = 2 V |
||||
| LED_COMP_HYST | 1:0 | R/W | LED headrom comparison hysteresis. This sets the MID comparator threshold.
00 = DRIVER_HEADROOM + 1000 mV 01 = DRIVER_HEADROOM + 750 mV 10 = DRIVER_HEADROOM + 500 mV 11 = DRIVER_HEADROOM + 250 mV |
