* The TPRO CTE clock requires special hardware to work. These tests
|
|
* ensure that the TPRO class properly handles cases in which no
|
|
* hardware is in use.
|

|
|
* Listed requirements are under requirement Trick-153 (3.7.1.2)
|
|
* Real-time control shall be able to use an external clock source
