Function of DATA MODE
DATA MODE switches external duty control (forced PWM control) and constant current CLK-IN control.
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.

Note 1: Normally, use CLK-IN mode.
9.
Electrical Angle Setting immediately after Initialization
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
current is not output.
Note that the initial electrical angle value in 2-Phase Excitation mode differs from that in nW1-2 (n = 0,
1, 2, 4) Phase Excitation mode.
