8. Function of DATA MODE
Note 1: Normally, use CLK-IN mode.
9. Electrical Angle Setting immediately after Initialization
Note 2: Where, IB = 100% and IA = 0%, the electrical angle is 0°. Where, IB = 0% and IA = 100%, the electrical

In Phase mode, H-bridge can be forcibly inverted and output only can be turned off. Constant current drive
including micro-step drive can only be controlled in CLK-IN mode.

Input
DATA MODE switches external duty control (forced PWM control) and constant current CLK-IN control.
In Initialize mode (immediately after RESET is released), the following currents are set.
In Low Power Dissipation mode, the internal decoder continues incrementing the electrical angle but
Note that the initial electrical angle value in 2-Phase Excitation mode differs from that in nW1-2 (n = 0,
