No, as far as I know the fr60 is absolutely software compatible to fr50 and= =20 fr30. The instruction set architecture did not change as well as interrupt= =20 exception handling. It seems, you are interested in Flexray.

The decision is up to you. I think porting to the MB91460 will be a bit eas= ier=20 because of the simpler architecture, but if you have done the MPC5567 you=20 will have a bit more fun with it. (I think I would also tend to the MPC...) Lars --nextPart1873588.IhfQgoWAaG Content-Type: application/pgp-signature; name=signature.asc Content-Description: This is a digitally signed message part.
