SCSI Description

3.5.5.1 Asynchronous Data Transfer

Drive to Initiator Transfer Procedure

1.The drive drives the DB (0-15, P, & P1) signals to their desired values.

2.Drive delays at least one deskew delay plus a cable skew delay.

3.Drive asserts the REQ signal.

4.Initiator reads the DB (0-15, P, & P1) signals.

5.Initiator indicates its acceptance of the data by asserting the ACK signal.

6.When ACK is true at the drive, drive can change or release the DB (0-15, P, & P1) signals.

7.Drive negates the REQ signal.

8.Initiator negates the ACK signal.

9.Drive can continue the transfer by driving the DB (0-15, P, & P1) signals and asserting the REQ signal (Steps 1 – 3).
