Microstepping
The driver is able to divide the single step into up to 16 microsteps. Stepping mode can be
programmed by STEP_SEL parameter in STEP_MODE register (see Table 19 on page 38).
Step mode can only be changed when bridges are disabled. Every time the 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.
