DATA phase:

Time taken for completing eight REQ/ACK handshakes (average).

Note:

When the ACK signal is returned repeatedly within an interval of

 

500 ms or more, timeout may occur even if eight REQ/ACK

 

handshakes on average had been terminated with the time listed in

 

Table 7.10.

When timeout is detected, the ODD clears the command being executed and forces the SCSI bus into the BUS FREE phase (see Section 6.1) in "MCD3130SS, MCE3130SS, MCK3130SS, MCM3064SS, MCM3130SS Optical Disk Drives SCSI Logical Interface Specifications."
