Frame information
This register can be used to double-check the number of images received by
the host computer against the number of images which were transmitted by
the camera. The camera increments this counter with every FrameValid sig-
nal. This is a mirror of the frame counter information found at 0xF1000610.
The FrameCounter is incremented when an image is read out of the sensor.
The FrameCounter does not indicate whether an image was sent over the
IEEE 1394 bus or not.
