ph KI Styles 2) The following questions are al up in view of the figures (ab) a) Describe what type of VO operation is carried out in Figure (a). Write an instruction Sague that will input the byte contents of input port 6 to memory location MEM1. b) What is the polling operation? Write a source of instructions to poll the input 1; at input port 5 ta chock whether it is switched to ter or not. Figure (a). c) Write a sequence of instructions that will read the contents of input port 7. Mask off all the bits except LSB. The content of LSB will be shifted to CF. CF-1, then the program will go to start of service routine XXX. Figure (a). d) Describe what type of 10 operation is carried out in Figure (b). Write a Fuence of instructions to initialize the control register in PPIO in Figure (b) so that PA is an output port, PR and Pc are input ports. Initialize all the necessary registers Ports are configured for made o operation. e) Write a program to input the contents of Pa and Pe then OR them together and send the resultant to PA. These ports are the PPIO ports in Figure (b). Ports are configured for mode operation. Initialize all the necessary egisters. Write comments and Use minimum number of instructions in your pro cams. ph KI Styles 2) The following questions are al up in view of the figures (ab) a) Describe what type of VO operation is carried out in Figure (a).
