a.Write the addressing modes of the following instructions: (i) MOV A, @R0 (ii) MOVX @DPTR, A (iii) MOVC A, @A+DPTR (iv) MOV R0, #45H b) Write instructions to perform the following operations: (i) Move the content of Accumulator to register 7(R7). (ii) Move the contents of RAM memory location 55H to Port 1 (iii) Receive content from ROM Memory location 200H into Accumulator. (iv) Clear bit 7 of the Accumulator. c) Why 4-20mA Current loop is widely used Industrial Standard for sensor data transmission and control. What are its advantages over 0-12V Standard? d) Two configurations of GPIB is shown in Fig. A and Fig. B. Explain the working of GPIB in both the configurations and what are the differences between the two.
