DSP通用Ｉ/O接口控制,系统时钟控制,DAM stop模式视频输出。实现DSP通用接口及按键控制，实现画面分割，内插图像成为ITU-R656 NTSC格式后输出到电视监视器上-DSP Universal I/O interface control, system clock control, DAM stop mode video output. To achieve common interface and button control DSP, based on the complete application of this design (programming Flash memory read out the image data, image segmentation 4, interpolation image as ITU-R656 NTSC format output to TV monitor, through the key test to switch the image, while driving lights).
