Microstepping
The driver is able to divide the single step into up to 16 microsteps. Step mode can be
programmed by the STEP_SEL parameter in the STEP_MODE register (see
Step mode can only be changed when bridges are disabled. Every time step mode is
changed, the electrical position (i.e. the point of microstepping sinewave that is generated)
is reset to the first microstep, and the absolute position counter value (see Section 6.5)
becomes meaningless.
