Low Power Dissipation mode
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,
Where, IB = 100% and IA = 0%, the electrical angle is 0 ° . Where, IB = 0% and IA = 100%,
DATA MODE inputs the external PWM signal (duty signal) and controls the current. Functions such as
Use this mode only when control cannot be performed in CLK-IN mode.

D MODE 2 → GA − (OUT A, A )
D MODE 3 → GB + (OUT B, B )
