R/W |
LED current sink headroom control, used for boost adaptive voltage control (boost low level) and open LED detection.
VSAT is the saturation voltage of the sink, typically 500 mV with 150-mA current.
111 = VSAT + 50 mV
110 = VSAT + 175 mV
101 = VSAT + 300 mV
100 = VSAT + 450 mV
011 = VSAT + 575 mV
010 = VSAT + 700 mV
001 = VSAT + 875 mV
000 = VSAT + 1000 mV |
