Applications
The SCSI bus has a total of 18 signals—9 are used for control, and 9 are used for data (one
parity bit). The bidirectional data lines transfer data, commands, status, and message infor-

ACK
Attention. Used to send a message to the target when it controls the bus.
Acknowledge. Used by the initiator for handshaking.
Reset. Used to initiate a bus-free phase.
Driven by the target to indicate that the current transfer is a message.
Select. Used by the initiator to select a target before command execution. Also used
by the target to reconnect when the reselection phase is implemented.
Control/Data. Used during the information transfer phases to transfer commands, sta-
tus, data or messages over the bus.
Request. Used by the target during information transfer phases.
Input/Output. Determines the direction of the transfer.
