2.6.3 System composition
SYSCON CPU adopted with this model has five data communication systems and communicates with
each peripheral device using those ports. There are three synchronous serial communication systems;
one of these is used only for the model having DSC function. The communication with the Camera DSP is
required a high-speed performance for transferring the information and command of camera auto
processing. Therefore, it is adopted the 16-bit parallel bus communication. And the asynchronous serial
communication (UART) is used for communication with external (PC, etc.).
