During HOLD active is the microprocessor executing anything ? or is it waiting the DMA finishing its task ?

This signal indicates that another master is requesting the use of the address.

Hold is input signal to Microprocessor, after handshaking Microprocessor gives control of address and data bus to DMA.
thankyou sirr
