The counter operation with interrupt transferring allows you to monitor the status of the counter operation without polling. When the counter reaches a specified count value, it will notify the driver through a hardware interrupt. These functions are only supported in the PCI-1750/1751.
The DRV_TimerCountSetting function configures the value of interrupt counts. The DRV_EnableEvent (true) function starts the counter operation. When it is running, use the DRV_CheckEvent function to check its status. When it reaches the count, it will return a hardware event.
To stop the counter, call DRV_EnableEvent(false) function again, and then reset the counter to to stop the operation by calling DRV_CounterReset.
