Intel 8051 is an 8-bit microcontroller. It has many powerful instructions and IO accessing techniques. In this section, we will see one of the simplest program using 8051.Here we will add two8-bit numbers using this microcontroller. The register A(Accumulator) is used as one operand in the operations. There are seven registers R0 – R7 in different register banks. We can use any of them as the second operand.We are taking two number 5FH and D8H at location 20H and 21H, After adding them, the result will be stored at location 30H and 31H.  AddressValue...20H5FH21HD8H...30H00H31H00H...ProgramMOVR0, #20H;set source address 20H to R0 ...
