8085 Program to find 2s complement of the number
Find the 2’s complement of the number stored at memory location 4200H and store
the complemented number at memory location 4300H.
For this example we have replaced address :
4200 -> 0700 and 4300 -> 0701
0700 25
LDA 0700
CMA
INR A
STA 0701
HLT
LDA 0700 – A 24 bits (3 bytes) command which will load content of memory location 0700 in register A i.e. Accumulator.
CMA – It will complement the binary value of Accumulator.
INR A – 1 byte command, it stands for Increment Register. It will add 1 to the value of register contain in this case it will add 1 to the value of accumulator.
STA 0701 – A 24 bits command which will store data of accumulator in memory location 0701.
HTL – It means Halt the microprocessor.
