Entry of external clock is enough to activate the micro step sinusoidal driver.
The excitation mode of 2, 1-2, W1-2, 2W1-2, or 4W1-2 can be selected with the external pin.
The 4-phase distributor switching timing can be set to occur either on both rising and falling edge detection or on
rising edge detection only with an external pin (MODE3).
A phase holding function is provided to prevent phase skip during switching of excitation in the course of operatio.
