3.1 Control/Sense Commands b) UNTATN (UNIT ATTENTION report mode) This specifies the response method to commands received from the INIT when the IDD is holding a UNIT ATTENTION condition: "1"* (Report): The IDD reports a CHECK CONDITION status (Standard SCSI specification) in response to commands other than INQUIRY and REQUEST SENSE. "0" (No Report): The IDD terminates all commands that are received normally. (A CHECK CONDITION status which causes a UNIT ATTENTION condition is not reported.) * Set at shipping time c) SDTR (synchronous data transfer request) Specifies whether or not it is permitted for the TARG to request a synchronous mode data transfer. "1" (Permitted) : After the power is switched on, after a RESET condition occurs or when the first command is received following reception of a BUS DEVICE RESET message, if a SYNCHRONOUS DATA TRANSFER REQUEST (SDTR) message is not sent by the INIT, the IDD sends the SDTR message and attempts to establish synchronous mode data transfer. "0"* (Prohibited): Even if it is necessary to establish synchronous mode data transfer, no SDTR message is sent from the IDD. However, if a SDTR message is sent from the INIT, the IDD responds normally. * Set at shipping time d) RSRTY (reselection retry) This specifies the number of retries in the RESELECTION phase. "1" *: Unlimited "0": 10 times * Set at shipping time e) PHSCRC (Phase CRC) This bit specifies where send or receive the CRC bytes in the DT Data IN/OUT transfer. "1" * (Phase): After the all transfer is terminated or before the phase during data transfer changes other phase, the CRC bytes are sent or recieved. "0" (Block): The CRC bytes are sent or recieved in each block boundary. * Set at shipping time The IDD ignores this specification and operates with the settings specified at shipping. C141-C010 3-17
