7-6 STEPSEL[1:0]
For table one or two scanning move step type selection.
(1) Bi-polar:
00 Full step (for 1939,1940,2916,6219 or 3966).
01 Half step (for 1939,1940,2916,6219 or 3966).
10 Quarter step (for 2916 or 6219).
11 Reserved.
(2) Uni-polar :
00 Two-phase-on full step.
01 Half step.
10 Reserved.
11 Single-phase-on full step.
5-0
MTRPWM[5:0]
To set PWM duty cycle for table one motor phase of uni-polar.
MTRPWM = 0 1/64 duty
= 1 2/64 duty
= 2 3/64 duty
……
= 63 64/64 duty
Note: If PHFREQ < 0FH,then PWM setting must < (PHFREQ+1)*4
