actual current
This status value provides the actual motor
current setting as controlled by coolStep™.
The value goes up to the CS value and down
to the portion of CS as specified by SEIMIN.
actual motor current scaling factor:
0 … 31: 1/32, 2/32, … 32/32

Stop on stall
Below this speed motor will not be stopped.
Above this speed motor will stop in case
stallGuard2™ load value reaches zero.

Ref. search mode
1
search left stop switch only
2
search rightstop switch, then search
left stop switch
3
search right stop switch, then search
left stop switch from both sides
4
search left stop switch from both sides
5
search home switch in negative
direction, reverse the direction when
left stop switch reached
6
search home switch in positive
direction, reverse the direction when
right stop switch reached
7
search home switch in positive
direction, ignore end switches
8
search home switch in negative
direction, ignore end switches
Adding 128 to these values reverses the
polarity of the home switch input.
