Unfortunately the manual is no longer available online, as this chip was phased quite a while ago. I can fax you the respective pages of my manual, if you like (send your number to christoph.nadig@stest.ch) Cheers, Christoph -- Christoph Nadig | mailto:christoph.nadig@stest.ch Switching Test Solutions AG | web :http://www.stest.com a Wandel & Goltermann Company | Phone : +41 1 454-6726 Friesenbergstr. 75 | FAX : +41 1 454-6605 CH-8055 Zurich | [[ This message was sent via the linuxppc-dev mailing list.
