   why is this useful? it turns out that these drives have a 1.75MHz signal recorded onto specific tracks, letting the MCU (which controls the stepper motor) know if it has gone outside of the data area.

   so basically, you step around, and if you see this pin go high (and stay high) then you know you're out of bounds.
