MVI Imm,[d],Z
Conditional transfer (Z=1 then Imm→[destination])
- Operation details
- When the Z flag is 1, Imm data is transferred to the RAM or register specified by [destination].
Imm data is signed 19-bit data.
It can also be used to execute a subroutine program by saving the value of the PC (jump destination address at the end of the subroutine) to TOP and transferring the Imm data (subroutine start address) to the PC (see instruction code * * ). Please note that in this case, the address next to this instruction will be executed twice, once before and after the subroutine execution.
