Multi-shot
Setting multi-shot and entering a quantity of images in Count_Number in
the 61Ch register enables the camera to record a specified number of images.
The number is indicated in bits 16 to 31. If the camera is put into Iso_Enable
mode (see Chapter ISO_Enable / free-run on page 187), this flag is ignored
and deleted automatically once all the images have been recorded.
If multi-shot mode is activated and the images have not yet all been cap-
tured, it can be cancelled by resetting the flag. The same result can be
achieved by setting the number of images to 0.
Multi-shot can also be combined with the external trigger in order to grab a
certain number of images based on an external trigger.
