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

| 23 | Description: |
| 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. |
