I know the datasheet says I can use an "external" clock if the device is in "XT" config, but obviously I don't want to use the OSCOUT of one device to drive the other since it's 1/4 the Frequency > This is only the case for RC drive. In any crystal configuration the OSCOUT is at the crystal frequency - it has to be in order to drive the crystal. -Adam > > -- http://www.piclist.com hint: The PICList is archived three different ways.
