Abstract
A method and apparatus providing a CMOS imager with an integrated controller on a common integrated circuit substrate. Also integrated on the common substrate are, a serializer circuit including a dynamic arbiter under the control of the microcontroller core and a set of extended special function registers through which data is passed to allow the microcontroller to control the CMOS imager and the serializer circuit.
