1.The 8051 microcontroller is of_pin package as aan-bit processor 2. The Stack Pointer of 8051 is of bit wide register and this may be defined anywhere in the byte RAM. 3. After reset, 8051 's Stack Pointer register is initialized to address. 4. What is the address range of SFR Register bank in 8051? 5. Given the instruction MOV @Ri. A, state the type of addressing mode used? 6. A CALL instruction in 8051 allows specifying byte address in the instruction and calls subroutine within byte program memory blook 7. Given the instruction MOVX DPTR, A, implies move the content of to extemal RAM of 16bit address indicated by 8. Write down a typical instruction used to set a bit on a port directly 9. Apart from Instruction Bus and Address Bus, is another bus by which the microprocessor communicate with the Memory and IO devices. 10. State which bus size is the same for both 8088 and 8086 11. A nibble correspond to s whereas a 10 byte correspond to 12. In 8086, the stack pointer is of 13. In 8085, name the 8 bit register that holds information after program execution 14. In which fashion does stack pointer works? 15 16. In 8086, when the sum is more than 16 bits the 17.8088 microprocessor has K bytes byte(s). addressing mode involve the use of a constant flag is set address lines whereas 8086 microprocessor has address lines. 18. Given A #20 decimal , C #01H ADD A, C INC A, What would be the content of A? 19. A 20-bit address bus allows access to a memory of capacity 20. Which interrupt in 8085 has the highest priority
