LVAL Pulse Counter
This 32-bit binary counter counts the Camera Link LVAL pulses.
The counter is not resettable:
- It is set to 0 at the driver initialization.
- As soon as the Camera Link de-serializers are initialized, it increments by 1 at every LVAL cycle whatever the acquisition conditions, i.e. whether the corresponding line data is acquired or not.
- It wraps around to 0 when it reaches the maximum count 4,294,967,295 (=232 -1).
Note: The counter is incremented before its value is inserted as metadata: the first line cycle
is marked 1.
