Fifth is internally developped by Philips (I believe in the mid 80's), so it is not strange to find many references.

Sounds nice, though I have not any practical experience with Atmel devices Albert --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "jallib" group.
