Q. No. 4: a. Differentiate between Isolated I/O and memory mapped I/O. b. Data are to be read in from two byte-wide input ports at addresses AAH and A9H and then output as a word-wide output port at address BO00H. Write a sequence of instructions to perform this input/output operation. c. List the differences between 8086 and 8088 MP architectures. Also describe the purpose of TEST, READY, LOCK, MN/MX and HOLD/HLDA pins of 8086/8088 MP.
