make and explain. Hint: Deteril bus cycle 1.6. Consider a computer system that contains an I/O module controlling a si keyboard/printer Teletype. The following registers are contained in the CPU andpe nected directly to the system bus: INPR: OUTR: FGI: FGO: IEN: Input Register, 8 bits Output Register, 8 bits Input Flag, 1 bit Output Flag, 1 bit Interrupt Enable, 1 bit Keystroke input from the Teletype and output to the printer are controlled by the WO module he Teletype is able to encode an alphanumeric symbol to an 8-bit word and decode an 8-bit word into an alphanumeric symbol. The Input flag is set when an 8-bit word enters the input register from the Teletype. The Output flag is set when a word is printed. Teletype is able t a. Describe how the CPU, using the first four registers listed in this problem, can b. Describe how the function can be performed more efficiently by also achieve I/O with the Teletype. employing IEN
