Question Paper
What are the purposes of EA, PSEN, ALE, XTAL1 and XTAL2
Compare the Data memory and Program memory of 8051 micro-controller.
Identify the Addressing mode in the following instructions
ADD #80H
ADD 74H
ADD @RO
MOV @A+DPTR
RL A
Write a program to fill a block of memory in the internal RAM with "AA".
Write a program to ADD two 16-bit Data stored in external memory locations. The first Data is stored in locations 4000H and 4001H, while the second is stored in locations 4002H and 4003H.
What are the different interrupt sources that 8051 has and how are they handled?
Mention and explain any five bit manipulating instructions.
How are based on the 8051 instructions classified
length of the instruction,
addressing mode, and
functions performed Give one example for each.
Write a program to transmit the ASCII character continuously using the 8051 serial port. Use 9 bit data at 9600 baud. Use polled operation.
Explain the different operating modes of serial ports of 8051.
Write a program to copy a block of 20 bytes of data available from Address 60H to 73H to the location starting from 40H.
What are the roles of interrupt and hardware reset in power management?
Explain the operational modes of Timer 0 and Timer 1 of 8051 micro-controller.
Assuming that 8051 micro-controller is interfaced with a 12 MHz crystal, develop a program to generate Timer 0 interrupts at every 50 milliseconds continuously.
Explain the Architecture of 8051 micro-controller with suitable diagrams.
Discuss the SFR associated with external interrupts.
An array of random integers is placed from internal data memory location 31H onwards. The number of terms of the array is available in the location 30H. Develop a program to place the entire array in reverse order in the same memory area.
Explain the interfacing of DAC (0808) with 8051.
10. Write short notes on any two of the following:
Microcontrollers and Microprocessors
Addressing modes of 8051
SFR processor status word
Memory organization of 8051
