In 8086 CPU working in the smallest way of microcomputer system, expand to design a data input ports, assigned to the port address 8001 h, the input port with 74 ls245 chip, input device for eight toggle switch,
1) draw this input port with the system bus and 8086 with the input equipment connection diagram,
(2) write a program to detect K0 switch, if K0 disconnect, program steering PROG1; K0 closed, and the program steering PROG2,
A program written for using proteus7.8 and emu8086
