23.2.3.1 Direction Change in Full Bridge Mode
In Full Bridge mode, changing the MODE[0] bit controls the forward/reverse direction. Direction changes occur on the next rising edge of the modulated input. The sequence, described as follows, is illustrated in Figure 23-8.
- 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.
