Functional description

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 Table 20 on

page 47).

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 sine wave that is generated)

is reset to zero, and the absolute position counter value (see Section 6.5) becomes

meaningless.
