Timing diagram for MVI R,8-bit data

E.g. MVI B,43H

This instruction is 2-byte instruction. Microprocessor takes two machine cycles (one is op-code fetch cycle for MVI B and another is memory read cycle for immediate data i.e. 43H) to complete the instruction. 

®    Fetching the Op-code 06H from the memory 2000H. (OF machine cycle)

®    Read (move) the data 43H from memory 2001H. (memory read)
