Strangely enough, I couldn't find it on the Philips site, but I knew it existed.

It's still on my CDROM 'IC20: 80C51-Based 8-bit Microcontrollers and Application Notes and Development bla bla bla'. Up to now, Philips people weren't able to remove it from this CDROM...

What an amount of wasted energy and menhours to develop such a chip and then to make it become obselete.

By the way, Arron should also read application notes EIE/AN93017 and perhaps AN438, if he wants total control on his 80C552...
