SV35 Series SATA Product Manual, Rev. B

If the value is 0, the drive shall use the Default Command Completion Time Limit supplied with the most recent
previous CONFIGURE STREAM command for this Stream type (Read or Write). If the Default Command Com-
pletion Time Limit is 0, or no previous Configure Stream command was defined for this Stream type, the result
is vendor specific. The time is measured from the write of the command register to the final INTRQ for com-
mand completion.
Error Outputs
If the RC bit is set to 0, the content of the registers shall be as shown below. If the RC bit is set to 1 and the
drive was able to transfer the correct amount of data (even though some of it may be incorrect), the SE bit shall
be set to 1, the ERR bit shall be set to 0.
ERROR REGISTER FIELD DESCRIPTIONS
ICRC (Interface CRC Error)
1 This bit shall be set to 1 if an interface CRC error has occurred during an Ultra DMA data transfer. The
content of this bit is not applicable for Multiword DMA transfers.
UNC (Uncorrectable)
1 This bit shall be set to 1 if data is uncorrectable. This bit should never be set on a streaming command.
IDNF
1 This bit shall be set to 1 if a user-accessible address could not be found. This bit shall be set to 1 if an
address outside of the range of user-accessible addresses is requested if command aborted is not
returned.
ABRT
1 This bit shall be set to 1 if this command is not supported. ABRT may be set to 1 if the device is not
able to complete the action requested by the command. ABRT shall be set to 1 if an address outside of
the range of user-accessible addresses is requested if IDNF is not set to 1.
