made does not take effect until the following new
frame.
For bits (5:0) = 0 to 5,
V_step = bits (5:0) * 200mV + 0.2V.
Range: 0.2 - 1.2V
For bits (5:0) = 6 to 63
V_step = bits (5:0) * 23.5mV + 1.62V
Range: 1.76-3.1V
Note: Equation and range are determined with the
assumption that VAA = 3.3V. They may vary with
actual VAA voltage.
Default: 2.54V
Usage: Vstep1 HDR voltage
