Unit = 320, Max = 640
e) Specify the packet size.
This camera is designed so that Unit is the minimum Frame Rate and Max is the maximum Frame Rate.
Set a value which is the integral multiple of the Unit and at the same time does not exceed the maximum value for the
packet size.
The range of isochronous transmission is determined by the packet size.
NOTE
: When ImagePosition/ImageSize/ColorCodingID are set at step d), the camera
recalculates and reflects the contents of CSR F1000140h PacketParaInq register.
If set so that the packet size is changed, be sure to perform this procedure.
f) Acquire the TotalBytes.
Image data size sent by the camera. For application softwares, secure a buffer of this size and prepare to receive data
transmitted isochronously.

ISO Enable ON
To stop the video, set the ISO Enable bit to 0.
(6) Video transmission start command (Format7)
When the following values are set for Status and Control registers for camera, the camera starts video transmission.
As there is no concept for the frame rate for Format7, the specification of CSR F0F00600h FrameRate will be ineffective.
