The Synthetic PIC Verion 1.1 This a VHDL synthesizable model of a simple PIC 16C5x microcontro

			 ;
			 ; MPASM Source code used for testing the Synthetic PIC
			 ;
			 ; TEST1:  Test basic data operations.
			 ;         You can use MPSIM to see what PIC *should* be doing and
			 ;         then comapre with VHDL simulation.
