illustrates operation in OPWMB mode with A1/B1 matches and the transition of the channel
output flip-flop. In this example EDPOL is zero.
Figure 17-53. eMIOS OPWMB Mode Example — Matches and Flags
The output flip-flop transitions are based on the negative edges of the A1 and B1 match signals.
shows the value of A1 being set to zero in cycle (n+1). In this case the match positive edge
is used instead of the negative edge to transition the output flip-flop.
