Interrupt driven mode of data transfer - 8085

Mention the steps in the interrupt driven mode of data transfer.

The steps followed in this type of transfer are as follows:

- The peripheral device would request for an interrupt.

- The request acknowledgement for the transfer is issued at the end of instruction execution.

- Now the ISS routine is initialized, The PC has the return address which is now stored in the stack.

- Now data transfer is managed and coordinates by the ISS.

- Again the Interrupt system is enabled and the above steps are repeated
