Solution:

The ADS_EVT_TERMINATED is not generated by DRV_DeviceClose or DRV_FAIStop. This event is generated while the drivers complete the number of ptEnableEvent.Count event. For example, user set the Non-Cyclic mode with the card which has the on-board FIFO, then this event will be generated while half or full of FIFO buffer. At this moment, user will be informed and user can transfer the FIFO data to PC memory for process.
