INTERNAL REGISTER DEFINITION
VCM DAC (High and Low) Registers
Bit 0 through 5 of the VCM DAC (High) Registers and bit 0 through 7 of the VCM DAC (Low) Registers
control the absolute value of the voice coil current. Bit is the sign bit, controlling the current direction. All
the 13 bits are part of a resistor divider network.
Note. It is required to write on register 1 to make effective changes on register 0.
