2. Add a pull down resistor on GPIO12 will indicate ASIC to turn off lamp power
in power-on initial state. This behavior is independent to setting of GPOM12.
3. This pin can control bipolar motor driver IC (2916,6219,3955 or 3967) Vref for
controlling Imax current when GPOM12 is set to
1
.
GPIO11: This pin can control bipolar motor driver IC (2916,6219,3955 or 3967) Vref for
controlling Imax current when GPOM11 is set to
1
.
