Timing diagram for INR M

  • Fetching the Opcode 34H from the memory 4105H. (OF cycle)
  • Let the memory address (M) be 4250H. (MR cycle -To read Memory address and data)
  • Let the content of that memory is 12H.
  • Increment the memory content from 12H to 13H. (MW machine cycle)

Timing diagram for MVI B, 43H.

  • Fetching the Opcode 06H from the memory 2000H. (OF machine cycle)
  • Read (move) the data 43H from memory 2001H. (memory read)
