An example showing how to add two large decimal numbers. Daa Instruction In 8085 Microprocessor

The necessity of DAA arises from the fact that binary addition of BCD numbers often yields "illegal" results. For example, adding decimal 9 (1001) and decimal 1 (0001) in binary results in 1010 (hexadecimal A). In BCD, however, the result should be 10, represented as 0001 0000. The DAA instruction detects these discrepancies and applies a correction factor to ensure the final value in the accumulator matches decimal logic. The between DAA in the 8085 versus the 8086 or Z80
