GET_VRSN returns various information on the chipset part number and
software version. The encoding is as follows:
Bit #
0-2
3-4

For example, the returned version code for the MC1401 (version 1.0
software) is 5908 (hex), the returned version code for the MC1201-P
(version 1.0 software) is 4928, and the returned version code for the
MC1241 (version 1.3 software) is 4a0b

GET_TIME returns the current systemtime, expressed as the number
of cycles since chip set power on.The chip set clock starts at 0 after a
power on or reset and will count indefinitely, wrapping froma value of
4,294,967,295 to 0. The returned value is a 32 bit number with units of
cycle times.

SET_PHASE_2 sets the current mcrostepping waveformto 2-phase.
With this waveformthe mcrostepping output signals have a phase
separation of 90 degrees, and can be used with standard 2-phase
stepper motors.
2-Phase mode is the standard waveform mode for most stepper
motors.

SET_PHASE_3 sets the current mcrostepping waveformto 3-phase.
With this waveformthe mcrostepping output signals have a phase
separation of 120 degrees, and can be used with 3-phase stepper
motors or 3-phase AC Induction motors.
