When using a camera with 8 parallel data ports to access the CIF, should the correspondence look like this?
Camera_D0-->CIF_D8
Camera_D1-->CIF_D9
Camera_D2-->CIF_D10
Camera_D3-->CIF_D11
Camera_D4-->CIF_D12
Camera_D5-->CIF_D13
Camera_D6-->CIF_D14
Camera_D7-->CIF_D15
Because I noticed that in the CIF driver there is as defined in the diagram。
If an 8-bit parallel data port camera is used, it will append 8 MSBs or Zeros as LSBs, which leads to the fact that when 8 data ports of the camera are connected to the low 8 LSBs of the CIF, data will be overwritten anyway if you want to use the sub-ISP functions correctly. And if only raw data is transferred(no sub-Cif function used), correspondence of connections does not matter。
The above is my understanding, is it correct?
Thank you!

If 8 data ports of the camera connected to 8 MSBs, then it looks like not impact.
