2. Draw for description of block diagram with flow signals (address, data and control) and timing diagram of an Intel-8088 microprocessor system to describe its operation when fetching and executing instruction (all data in hexadecimal) AND AL, AH; machine languge of this instruction: 22h-C4h With given data before execution this instruction: CS-3000, IP-4000, AL=0F0h, AH=0Fh What are physical address of this instruction before and after excution? What flag will be changed after executing this instruction? (4p: block diagram 1p, flow signal 1p and 1 and timing diagram 2)
