Interface units of the type shown in Figure are connected to a CPU that uses an I/O address of eight bits. Each one of the six chip select (CS) inputs is connected to a different address line. Specifically, address line 0 is connected to the CS input of the first interface unit, and address line 4 is connected to the CS input of the sixth interface unit. Address lines 7 and 6 are connected to the RS1 and RS0 inputs, respectively, of all six interface units. Determine the 8-bit address of each register in each interface (a total of 24 addresses).
