Design and build an Atmega2560 address decoder circuit for the 82C55 mapped as external DATA

memory with a base (beginning) address of C800H using partial address (allow the 82C55 to

foldback for 256 byte -> decode only address bits A15 through A8) decoding. Show the work for

each step of your design including the memory map, memory address table, Boolean equation, and

logic circuit diagram.
