Question

Which of the following in 8085 microprocessor performs HL = HL + HL?

• A. DAD D
• B. DAD H
• C. DAD B
• D. DAD SP

Hint:

For HL = HL + HL, use DAD H. The DAD instruction is specific to register pairs.

Answer 1

The Correct Option is B

The DAD (Double Add) instruction in the 8085 microprocessor adds the contents of a specified register pair to the contents of the HL register pair. DAD H adds HL to itself, effectively performing HL = HL + HL.
