It allows a larger address space with a small instruction word. Bank switching is a legitimate trick to reduce processor cost at the expense of some extra instructions required in the firmware. What I get fed up with is people doing stupid things like hard coding the BCF or BSF instructions on the bank bits, then asking us what's wrong with their program. ***************************************************************** Embed Inc, embedded system specialists in Littleton Massachusetts (978) 742-9014, http://www.embedinc.com -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY!
