7-0 RATED_VOLTAGE_CLAMP[ R/W
7:0]
100 This parameter is to set a clamp for the steady state voltage provided by the driver. This clamp
is enforced after the overdrive section of the waveform. Note that if the OD_CLAMP is lower
than this parameter, the lower clamp will be applied. The same is true if the
BAT_LIFE_EXT_LVLx is triggered.
