Interface an 8255 with 8086 to work as an I/O port. Initialize port A as input port, port B as output port and Port C as an output port. Port A address should be 0780h. Write a program to sense switch position SW0-SW7 connected at port A. The sensed pattern is to be displayed on Port B, to which eight LEDs are connected, while the port C upper displays number of ON switches out of the total eight switches.
