One capture input port can be used for 656 format only, whereby the other can select between RGB
format and 656 format.
To use 656 input via the port which can handle both RGB and 656, check the pin multiplex tables in
this Hardware Manual to obtain the details about external pin routing.
Use the VIS bit of the VCM
The input port is selected using the Csel0/1 bit of the VCCC (Video/Capture Common Control) register.
Csel0 = 0: 656 input → Capture 0
Csel0 = 1: RGB/656 input → Capture 0
Csel1 = 0: 656 input → Capture 1
Csel1 = 1: RGB/656 input → Capture 1
