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 the which of two frames is input to the CCDC module for sensors with interlaced output. CCDC handles 1- or 2-field sensors in hardware. GIO: GIO[083]
