Table 266 Write Stream Ext Command (3Bh)
This command writes from 1 to 65536 sectors as specified in the Sector Count register. A sector count of 0 requests
65536 sectors.
If the Write Continuous (WC) bit is set to one, the device shall not stop execution of the command due to errors. If
the WC bit is set to one and errors occur in the transfer or writing of the data, the device shall continue to transfer the
amount of data requested and then provide ending status with the 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, reported 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 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 event if some data
transferred is in error.
