0013 Description:
0014 Sends an FSI BREAK command on a master's communication
0015 link to any connected slaves. A BREAK resets connected
0016 device's logic and preps it to receive further commands
0017 from the master.

0023 Description:
0024 Sends an FSI terminate command from the master to its
0025 connected slave. A terminate resets the slave's state machines
0026 that control access to the internally connected engines. In
0027 addition the slave freezes its internal error register for
0028 debugging purposes. This command is also needed to abort any
0029 ongoing operation in case of an expired 'Master Time Out'
0030 timer.
