Ummmm... yes, there are. Especially if you want to use it as  a  host
comtroller  (which  is  never  was designed for). Even more, if there
might be other periopherals in your system that might need  a  bit  a
CPM performance. Or ...

No, I better stop here. Please ask your  Freecale  sales  representa-

You can do that. Anything can be done. But in this case I don't  know
of an efficient way to do it. But my knowledge is limited, obviously.
