Write enable input signal is used by external device (AFE/TG) to gate the DDR output of the CCDC module. Alternately, the field identification input signal is used by external device (AFE/TG) to indicate which of two frames is input to the CCDC module for sensors with interlaced output. CCDC handles 1- or 2-field sensors in hardware.

2.4.2Image Data Output - Video Processing Back End (VPBE)

The Video Encoder/Digital LCD interface module in the video processing back end has an external signal interface for digital image data output as described in Table 2-7and Table 2-8.

The digital image data output signals support multiple functions / interfaces, depending on the display mode selected. The following table describes these modes. Parallel RGB mode with more than RGB565 signals requires enabling pin multiplexing to support (i.e., for RGB666 mode).
