Olin, "FAST" in this application means that I want to decode the incoming = Serial bytes=20 up to 64K Baud as they arrive with "plenty" of time left to do other = tasks between UART interrupt for next byte. "plenty" =3D as much as I can get. as opposed to "not much" meaning very = little time=20 to perform other tasks. The oscillator is 16 MHz. I do not want to = increase the oscillator frequency or use the 4 x PLL. where "other tasks" vary depending on the application.

This is a useless question without defining "fast". I've got a PIC decoding two "fast" received manchester streams serially bit by bit, and it's doing a few other things at the same time. So, how fast is "fast"? ***************************************************************** 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!
