• 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."
