n lines saved in DRAM for every m lines (register 44)
scanned, function bypassed if register value = 0.
n (lines saved per m lines scanned) = 256 - t
t = 256 - n
If t = 0 then function is bypassed.
n lines (register 43) saved in DRAM for every m lines
scanned. m = 1 to 255.
If m = 0 then function is bypassed.

2 Phases - necessary for microstepping
Positive (A/B/A/B Output high = winding energized)
Negative (A/B/A/B output low = winding energized)
WARNING: When idle, this setting leaves the motor
energized for unipolar motors, and will destroy bipolar
motor drivers. Keep this bit set to a 0.
