The signal is generated continuously. |
auto |
| The signal is generated continuously; a trigger event causes a restart. |
retrig |
| The signal is started only when a trigger event occurs; subsequent trigger events are ignored. |
armed auto |
| The signal is started only when a trigger event occurs; every subsequent trigger event causes a restart. |
armed retrig |
| The signal is started only when a trigger event occurs; signal is generated once. |
