Figure 17-43. eMIOS OPWFMB Mode Example — A1/B1 Updates and Flags
shows the operation of the output disable feature in OPWFMB mode. Unlike OPWFM mode,
the output disable forces the channel output flip-flop to the EDPOL bit value. This functionality targets
applications that use active high signals and a high to low transition at A1 match. For such cases EDPOL
should be 0.
