--E0t4Q5czbJHEOOyHvpgHBLZv9uj2oylb3KhII4m Content-Type: text/plain; charset=US-ASCII Content-Transfer-Encoding: 7bit I'm not certain but I don't think routing the pin to two emios channels is possible. If an ETPU function doesn't exist, you could certainly write one to do this. The easy work-around is to tie two EMIOS pins together externally and use one channel for each function, but I presume you are trying to preserve resources. - Allan ________________________________ From: [email protected] [mailto:[email protected]] On Behalf Of [email protected] Sent: Wednesday, September 09, 2009 1:57 PM To: [email protected] Subject: RE: [MPC500] MPC5500 eMIOS functions Can a connection to a single eMIOS pin be internally routed to two eMIOS channels?
