13a7ec9371SChristopher BosticDescription:
14a7ec9371SChristopher Bostic		Sends an FSI BREAK command on a master's communication
15a7ec9371SChristopher Bostic		link to any connnected slaves.  A BREAK resets connected
16a7ec9371SChristopher Bostic		device's logic and preps it to receive further commands
17a7ec9371SChristopher Bostic		from the master.

23a7ec9371SChristopher BosticDescription:
24a7ec9371SChristopher Bostic		Sends an FSI terminate command from the master to its
25a7ec9371SChristopher Bostic		connected slave. A terminate resets the slave's state machines
26a7ec9371SChristopher Bostic		that control access to the internally connected engines.  In
27a7ec9371SChristopher Bostic		addition the slave freezes its internal error register for
28a7ec9371SChristopher Bostic		debugging purposes.  This command is also needed to abort any
29a7ec9371SChristopher Bostic		ongoing operation in case of an expired 'Master Time Out'
30a7ec9371SChristopher Bostic		timer.
