8085 Program to find 1s complement of the number
Find the l’s complement of the number stored at memory location 4400H and store the complemented number at memory location 4300H.
For this example we have replaced address :
4400 -> 0700 and 4300 -> 0701
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.
STA 0701 – A 24 bits command which will store data of accumulator in memory location 0701.
HTL – It means Halt the microprocessor.
