This is relative value from reference value (128d). So the absolute value of threshold is 128d + ON[6:0].
It makes a threshold value between TH_ON and TH_OFF.
TH_ON must be bigger than TH_OFF (TH_ON >= TH_OFF)
Maximum threshold is 256d and minimum value is 128d.
This register provides a threshold value for transitioning from ON to OFF.
This is relative value from reference value (128d). So absolute value of threshold is
128d + OFF[6:0]. It makes a threshold value between TH_ON and TH_OFF.
TH_OFF must be smaller than TH_ON (TH_OFF =< TH_ON)
Maximum value is 256d and minimum value is 128d.
