A generic microcontroller has eight data lines and eight address lines. This device is to be connected to four 16 x 8 bit ROM modules. Each ROM has 4 address pins, 8 data pins and a single pin that functions as both a Chip Enable and Read signal. i) Illustrate in a diagram how the ROMs can be interfaced with the microcontroller in such a way that they can be individually accessed without any additional logic gates.
