INTERNALREGISTER DEFINITION
VCM DAC (Highand 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 absolutevalue of the voice coil current. Bit is the sign bit, controlling the current direction. All
the 13 bitsare part of a resistordivider network.
Note. Itis requiredto write on register 1 to make effectivechangeson register 0.
