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

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