Hmm.. should have looked into the header =) Guess I'll have to check the clock circuit physicaly.. The reason for asking is to explore a way to sample signals asynchronously. But useing timestamps to calculate how it looks when sampled synchronously. Thus avoiding the need for fifo circuitry. Btw, avoid html encoded email pls. _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
