You are asked to write two programs in Hack assembly language. You should use the stock 16-bit Hack machine in this project, running on the CPU emulator. an interactive program called toggle.asm which flips the colour of the screen (from black to white or white to black) every time a keypress is released, i.e. when the keyboard moves from a ‘key pressed’ to a ‘no key pressed’ state. (Simultaneously pressing multiple keys, or switching from one key to another while always having some key pressed, should not cause a change—only when all keys are released should the flip occur.)
