Description:
|
|
Sends an FSI BREAK command on a master's communication

|
|
device's logic and preps it to receive further commands

from the master.

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