In addition, it can be configured as Interlace or Non-Interlace mode depending on the input pattern from external image.
The CSC Image Capturer is also designed with programmable bus occupation rate and access time to maximize the
efficiency of Local Bus (upper-layer AMBA in the case of EAGLE) for applications on Multi-Master System.
