9.1.3 Direction Control Time Constant

The time constant for the direction control function can be set by the control mode pins, DIRSET1 and DIRSET2. These pins should be set to correspond to the desired data rate. With no external connections to the control mode pins, the internal time constant is set to the maximum value, corresponding to the minimum data rate.
