Counter and Timer Control Function (counter support only)

The counter function counts up change points in the camera's internal signals using the camera's
internal counter, and reads that information from the host side. This function is useful for verifying error
conditions via the count value using internal camera operations.
Counting is performed at frame trigger, frame start, exposure start, and exposure transfer end, and
by comparing these values, you can determine the internal camera state at which missed triggers will
occur.
