1. Outputs at integer-related frequencies and using the same driver format. See "3.9.3. Initial Phase Offset" on page 24.
2. The maximum step size is only limited by the register lengths; however, the MultiSynth output frequency must be kept
3. Update rate via I
4. Default value is 0.5% down spread.
5. Default value is ~31.5 kHz.
