1 This bit specifies that all data for the specified stream shall be flushed to the media before command
complete is reported.
CCTL (Command Completion Time Limit)
The time allowed for the current command to complete. This value is calculated as follows:
CCTL = (content of the Features register Previous) * (IDENTIFY DEVICE data words (99:98)) microseconds
0 The device shall use the Default Command Completion Time Limit supplied with the most recent previ-
ous CONFIGURE STREAM command for this Stream type (Read or Write). If the Default Command
Completion Time Limit = 0, or no previous Configure Stream command was defined for this Stream ID,
the result is vendor specific. The time is measured from the write of the command register to the final
INTRQ for command completion.
Error Outputs
If the WC bit is set to 0, the content of the registers shall be as shown below. If the WC bit is set to 1 and the
drive was able to transfer the correct amount of data (even though some of it may be written incorrectly to the
media), the SE bit shall be set to 1 and the ERR bit shall be set to 0.
ERROR REGISTER FIELD DESCRIPTIONS
ICRC
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.
