In 8085 Instruction set, MOV is a mnemonic, which stands for “MOVe”. In this instruction 8-bit data value in register r2 will be moved to the 8-bit register r1. Note that in 8085 instructions, as the first operand specifies the destination, and the second one the source, so here also r1 is destination register and r2 is the source register. This instruction uses register addressing for specifying the data. Here, “r1” and “r2”can be any one of the following registers. r1, r2 = A, B, C, D, E, H, or L As r1 can have any one of ...
