Question 5 a) Interrupts allow computers (microprocessor) to multitask, carrying out many tasks or having several windows open at the same time. Operating systems have some code called an 'interrupt handler', which prioritizes the interrupts and saves them in a queue. With this background and in your own words analyses the various interrupts in 8085 microprocessors and give specific examples. (7 marks) EV b) A clerk officer found out that his pen is missing so he decided to go to the market to purchase one. With the various steps taken by the officer, apply techniques of flowcharts to design a workable system. (8 marks) CR TOM RD WR IOR IOW In peripheral mapped I/O interfacing the I/O devices are treated differently from memory chips. The control signals I/O read (IOR) and I/O write (IOW), which are derived from the IO/M, RD and WR signals of the 8085, are used to activate input and output devices, respectively. Generate these control signals in a truth table to show the status of 10/M, RD and WR signals during I/O read and I/O write operation (5 marks) AN
