CCTL (7:0)
URG specifies an urgent transfer request.
specifies that the command should be completed in the minimum
possible time by the device and shall be completed within the
specified Command Completion Time Limit.
RC specifies Read Continuous mode enabled.
tinuous bit is set to one, the device shall not stop execu-
tion of the command due to errors.
If the RC bit is set to one and errors occur in reading or
transfer of the data, the device shall continue to transfer
the amount of data requested and then provide ending status
with BSY bit cleared to zero, the SE bit set to one, the ERR
bit cleared to zero, and the type of error, UNC, IDNF or ABRT
reported in the error log.
If the RC bit is set to one and the CCTL expires, the device
shall stop execution of the command and provide ending status
with the BSY bit cleared to zero, the SE bit set to one, the
ERR bit cleared to zero, and report the fact that the CCTL
expired by setting the CCTO bit in the error log to one.
In all cases, the device shall attempt to transfer the amount
of data requested within the CCTL even if some data trans-
ferred is in error.
NS (Not Sequential) may be set to one if the next read stream
command with the same Stream ID may not be sequential in LBA
space.
HSE (Handle Stream Error) specifies that this command starts
at the LBA of the last reported error for this stream, so the
device may attempt to continue its corresponding error recov-
ery sequence where it left off earlier.
Stream ID specifies the stream to be read.

command.

If the value is zero, the device shall use the Default CCTL
supplied with a previous Configure Stream command for this
Stream ID. If the Default CCTL is zero, or no previous Con-
figure Stream command was defined for this Stream ID, the
device will ignore the CCTL.
