The default Command Completion Time Limit (CCTL).
The value is calculated as follows:
(Default CCTL) = ((content of the Features register)*
(Identify Device words (99:98))) micriseconds.
This time shall be used by the device when a streaming
command with the same stream ID and a CCTL of zero
are issued.
The time is measured from the write of the
command register to the final INTRQ for command
completion.
