2. The PWM output pins remain in a high-impedance state until this parameter is specified.
3. This parameter must be specified before motor motion can be initiated by the MC3PHAC.

5. The value of this parameter is not valid until the PWM outputs exit the high-impedance state.
6. The data in this field is only valid for one read. Further reads will return a value of $00.
7. See register bit descriptions following this table.
8. Acceleration is an unsigned value with the upper seven bits range of $00 to $7F = acceleration value of 0 to
