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

Question

In case of DMA, after the completion of the transfer, the processor is required to be notified of the completion. This is done through.

Answer 1

The 8085 microprocessor's DAD (Double Add) instruction adds the contents of a specified register pair to the HL register pair. For example, DAD H adds the HL register pair to itself, which effectively performs HL = HL + HL.

List I	List II
A. Supervisor mode	I. Entered when the processor encounters a software interrupt instruction
B. Abort Mode	II. Entered in response to memory fault
C. Fast Interrupt Mode	III. Entered whenever the processor receives an interrupt signal from a designated fast interrupt source
D. Interrupt Mode	IV. Entered whenever the processor receives an interrupt signal from any other source

Firm 2	Cooperate	Compete
Firm 1	5, 5	0, 10
Compete	10,0	2, 2
