The image FIFO size is 2Gb. Images are stored in the memory at 10bits per pixel. The next table
shows the number of images at full resolution that can be stored. This number scales with ROI.

Max full image capacity Table 7.10:
For a given ROI where ROI width indicates the width of the ROI and ROI height indicates the height,
the maximum burst size (at 10 bit output resolution) nmax equals:
where:
nmax = number of frames
Memsize = 231 / 10 pixels, which is approximately 214Mpix
NOTE: ROI width is subject to restriction, see the ROI section.
nmax is limited to 2

Request mode 7.6.2.
The camera can transmit the captured data over the interface directly or upon request. This is selected
by means of the Request Mode command.
The mode in which the images are output is programmable by means of the RQM command.
Command format: RQMx
Command format: RQM?
Return Message: x
where x indicates the Request Mode according to the following table.
x Request Mode
0 Images are output immediately after acquisition. If acquisition takes place at a speed that the
Camera Link interface can manage (e.g. at 8-Taps 85MHz at 4Mp this is 167 fps or slower) the
FIFO will not fill up and cause a delay.
If acquisition runs faster than the Camera Link output allows, images will temporarily be
stored, but output immediately once the interface is ready for them.
1 A fixed number of images is output upon receiving a request pulse or an RQ command.
The number of images is set by means of the RQSIZE command
2 All images available are output upon receiving a request pulse or an RQ command.
Request modes Table 7.11:
In RQM2 and RQM3, the request can be made via a command, CC pulse or hardware trigger (see
section 7.6.3).
NOTE: A situation of acquisition speed exceeding the maximum Camera Link speed can only be
maintained for a limited amount of time (burst mode). Else, the buffer will overflow.
