What is the simple program for 8bit addition using 8085 microprocessor?
Suppose you want to add 11 and 12.instruction are : mvi a,11h mvi b ,12h mov d,b add b
Can Mov used in 8085 for immediate data transfer?
No, not at all this instruction MOV can not be used for immediate data transfer. You will need to use command MVI Rd, 8 Bit Data for immediate data transfer.
How data transfer operation is done in 8085 micro processor?
Data transfer in the 8085 microprocessor can be done with the help of several instructions like the MOV,MVI,OUT and IN . Lets say, we want to move the contents of a register R1 to register R2, then we could use the instruction MOV R2,R1 ; and so on...
