Cs609 Current Mid term paper 1. coprocessor Control word usage in testing of coprocessor 2. write the function of this code (char hi, char lo) hi= hi – 0x30; lo = lo – 0x30; hi= hi | lo; return hi; 3. How we can access the battery powered RAM? Write steps? 4. Why we use buffering in UART FIFO queue? 5. In line control register what is the working of bit # 7? 6. What is serial communication? Explain it. 7. In flow control what is the working of D4? 8. How can we enable the 0x0f to perform interrupt driven I/O? Write a program. 9. In 13/3H service what is the value of AX and BX? CS609 Mid Term current Papers Spring 2011, (May 2011) Total 23 questions 16 mcqs. of 1 mark each. 2 questions for 2 mark each write the port number connected to LPT ports. what is com port write the service number and describe. 2 questions for 3 marks each Can we send the data to keyboard if yes then justify your answer, if no then give the reason. what is UART ? 2 questions for 5 marks each Write a program to hook up the modem with processor, also write the separate routine for control the modem, line status, generate the signal. What is co-processor, describe the role of co processor and write the routine to attache the co processor with processo another paper coprocessor Control word usage in testing of coprocessor write the function of this code (char hi, char lo) hi= hi – 0x30; lo = lo – 0x30; hi= hi | lo; return hi; How we can access the battery powered RAM?
