5-4 GPOM[12:11]
To select GPIO12~11 as Bi-polar motor driver V-ref input voltage in order to
control drive current.
Note: GPIO12: 1. Pull up by resister to indicate that ASIC turn on lamp power
whenever power on initial.
2. Pull down by resister to indicate that ASIC turn off lamp
power whenever power on initial.
3. This pin can control bi-polar motor driver 1939,1940,2916,
6219 or 3955 Vref in order to Control Imax. current.
GPIO11: This pin can control bi-polar motor driver 1939,1940,2916,6219
or 3955 Vref in order to Control Imax. current.
