Assume that the accumulator contains data byte 82H and instruction MOVC, A(4FH) is fetched. List the steps in decoding and executing instruction.


Assume that the accumulator contains data byte 82H and instruction MOVC, A(4FH) is fetched. List the steps in decoding and executing instruction.

       The contents of the accumulator are specified. To decode and execute the instruction, the following steps are performed :

  1. The contents of the data bus (4F) are placed in the instruction register and decoded.
  2. The contents of the accumulator (80) are transferred to the temporary register in the ALU.
  3. The contents of the temporary register are transferred to register C.
