Frequency based speed control is configured by setting SPD_CTRL_MODE to 11b. In this mode, duty command varies linearly as a function of the frequency of the square wave input at SPEED pin as given in Equation 4. Input frequency greater than INPUT_MAX_FREQUENCY clamps the duty command to 100%. The duty command is set to zero and the motor is stopped when the frequency signal at SPEED pin stays < VDIG_IL for longer than tEN_SB_FREQ.
