The basic CPU cor= e registers are always in the access bank, but on some PIC 18 there are too many peripheral registers and some of them end up in banked memory. This i= s the case for the CAN and ethernet parts, for example. It think it's also the case for some very large parts with lots of port/tris/lat registers if = I remember right. ******************************************************************** Embed Inc, Littleton Massachusetts, http://www.embedinc.com/products (978) 742-9014.
