WC specifies Write Continuous mode enabled.
Continuous bit is set to one, the device shall not stop ex-
ecution of the command due to errors.
If the WC bit is set to one and errors occur in transfer or
writing 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, IDNF or ABRT re-
ported in the error log.
If the WC bit is set to one and the Command Completion Time
Limit 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 Command Completion Time Limit 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 Command Completion Time Limit
even if some data transferred is in error.
F specifies that all data for the specified stream shall be
flushed to the media before command complete is reported when
set to one.
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
recovery sequence where it left off earlier.
Stream ID specifies the stream being written.
shall operate according to the Stream ID set by the Write
Stream command.
The time allowed for the current command's completion is cal-
culated as follows:
Command Completion Time Limit = (content of the Feature
register
(99:98)) seconds
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
Configure Stream command was defined for this Stream ID, the
device will ignore the CCTL.
