Q.4: Choose the right answer for the following:1. Which of the following port addresses cannot be assigned to port A of the 82C55APPI, and why?а-34hb- 41hc-9Ahd- 89h2. What is the duration of bus cycle in 8086 MPU if the clock is 20 MHz and two waitstates are inserted?a- 50 nsec b-200nsec c-250nsec d- 300nsec3. If READY pin is grounded, it will introduce -----state into the bus cycle of the 8086MP.c- waita- high4. The 74ALS138 has total of ---- outputs.a- four b- 16 c- ten d-85. When A0-0, it makes the address an -b- nod- lowaddress.a- I/Ob- evenc- odd d- extra6. If the oscillation frequency of 8284A clock generator is 24 MHz, the clock signalfrequency is----- a-4 MHz b- 20 MHz c-8 MHz d- 6 MHz7. If the oscillation frequency of 8284A clock generator is 24 MHz, the peripheralfrequency is------ a-4 MHz b- 20 MHz c- 8 MHz d- 6 MHz8. In fully buffered 8086 microprocessor, its address pins are already buffered by...a- two 74LS373 address latchesb- three 74LS245 address latchesc- three 74LS373 address latches9. The RES input to the 8284A is placed at logic --- level in order to reset the 8086.d- two 74LS245 transceiverа- 00 b-01 с-10d- 1110. If I/O port address in PPI 82C55 by using a 74ALS138 ( to generate high-bank I/Oaddress) is 1DH, then it used to address:a- PPI5, PB b- PPI7,PB c- PPI5,PC d- PPI7,PC
