0 votes 0 votes In Daisy Chain First INTA is sent by CPU to I/O devices which are present in a row, the device which raises the interrupt earlier will take this signal and send Vector Address to the CPU. (Other devices which are present before the device which raises the interrupt will just pass the signal to next device present in the row until it reaches to final one).
