- Consider a computer system that contains an I/O module controlling a simple keyboard/printer teletype. The following registers are contained in the processor and connected directly to the system bus: INPR: Input register – 8 bits OUTR: Output register – 8 bits FGI: Input flag – 1 bit FGO: Output flag – 1 bit IEN: Interrupt enable – 1 bit Keystroke input from the teletype and printer output to the teletype are controlled by the I/O module. The teletype is able to encode an alphanumeric symbol to an 8-bit word and decode an 8-bit word into an alphanumeric symbol. Describe how the processor, using the first four registers listed in the problem can achieve I/O with the teletype. Describe how the function can be performed more efficiently by also employing IEN.Computer Science Please answer this question in assembly language with .asm extension.
