3.2 Video General Serial Interface
This interface is reserved to control an external camera or an LCD. It is not supported now.
3.3 Video Camera Interface
A CMOS Camera or a CCD Camera is connected via Toshiba CMOS camera
DSP ”TC90A50F” or ”TC90A70F”, or an ordinary NTSC decoder LSI. Fig.6, 7, 8 shows the
timing diagrams of the camera signal input. When an NTSC decoder is used, TC35273
captures either an odd field or an even field by using CAMFSEL.
