My boss gave me an embedded device with a 8051 processor coupled to a SCC2692 (by Philips) uart and the Keil c compiler. Now I was ordered to develop some kind of pc-interface. The problem now is: I have absolutely now idea how to access this SCC2692 uart. I have documentation the chip, but how am I supposed to fiddle with it? Is it memory mapped? Does the 8051 have special io-instructions? All help is appreciated!
