HALF-STEP/FULL-STEP
The AA2920A operates a motor in either half-step or full-step operation. In half-
step mode, the motor is stepped by alternately energizing one phase, and then two
phases of the motor. With a 1.8 degree motor (200 steps/rev), half-step mode will
provide 400 steps/revolution. Table 2 below shows the sequence for half-step.

Table 2: Half-step Phase Sequence 1=ON, 0=OFF
In Full-step mode, there are always two phases on at a time. The motor is stepped
by turning off a phase and turning on the opposite phase (i.e. - turn phase 1 off and
turn phase 3 on). A standard 1.8 degree motor will provide 200 steps/revolution in
full-step mode. The phase sequence for full-step is shown in figure y2.
