Suppose, two different "byte-wide" input devices (i.e. each input is 1 byte in size) are connected to the ports of an 8086 microprocessor located at address FAh and 9Ah, and another word-wide output device (i.e. each output is 2 bytes in size) is connected to the port located at the address FA8AH. Now, write an assembly code snippet that does the following- a. Read 1-byte data from each of the two input devices b. Combine these 2 bytes of data into word data. Byte data that came from address FAh should go to the high byte in the word. c. Write the word data to the output device.
