    Speed up CyU3PDmaMultiChannelSetWrapUp.

      Hello,

         

      we're working with a multi-channel manual-out dma on the FX3, but we noticed that wrapping up a 32 Kb buffer takes very long time (CyU3PDmaMultiChannelSetWrapUp takes 160 us while a single CyU3PDmaMultiChannelCommitBuffer takes about 10 - 20 us).

         

      Is there a way to speed up the wrap up? Why does it take so much?

         

      Thank you very much.
