Questions answered in these manuals
Which pin enables or disables the driver output?
The ENABLE pin is active low; when it is low the output is forced off, and when high the driver operates normally.
How do I set the microstepping mode?
Microstepping is selected using the ML, M2, and M3 pins; each pin corresponds to a specific division factor such as 1/2, 1/4, 1/8, etc.
