13Description:

15		link to any connected slaves.  A BREAK resets connected
16		device's logic and preps it to receive further commands
17		from the master.

23Description:
24		Sends an FSI terminate command from the master to its
25		connected slave. A terminate resets the slave's state machines
26		that control access to the internally connected engines.  In
27		addition the slave freezes its internal error register for
28		debugging purposes.  This command is also needed to abort any
29		ongoing operation in case of an expired 'Master Time Out'
30		timer.
