COMMAND SENDING PROCEDURE UNTIL IMAGES ARE DISPLAYED

e) Specify the packet size.

Address	Action	Data

F1000140h	Read	02800140h	Unit = 320, Max = 640

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.

Address	Action	Data

F1000144h	Write	02800000h	Packet size = 640

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.

Address	Action	Data

F1000138h	Read	00096000h	Lower 32 bits

F100013Ch	Read	00000000h	Upper 32 bits

Image data size sent by the camera. For application softwares, secure a buffer of this size and prepare to receive data transmitted isochronously.

(6)Video transmission start command (Format7)

When the following values are set for Status and Control registers for camera, the camera starts video transmission.

Address	Action	Data

F0F00604h	Write	00000000H	Video Mode = 0

F0F00608h	Write	E0000000H	Video Format = 7

F0F0060Ch	Write	12000000H	ISO ch = 1, Speed = 400M bps

F0F00614h	Write	80000000H	ISO Enable ON

To stop the video, set the ISO Enable bit to 0.

Address	Action	Data

F0F00614H	Write	00000000H	ISO Enable OFF

As there is no concept for the frame rate for Format7, the specification of CSR F0F00600h FrameRate will be ineffective.
