In Full-Bridge mode, changing MODE controls the forward/reverse direction. Direction changes occur on the next
rising edge of the modulated input.
A direction change is initiated in software by changing the MODE
bits. The sequence is illustrated in Figure 1.
- The associated active output CWGxA and the inactive output CWGxC
are switched to drive in the opposite direction.
- The previously modulated output CWGxD is switched to the
inactive state, and the previously inactive output CWGxB begins to modulate.
- CWG modulation resumes after the direction-switch dead band has elapsed.
