NOTE 1: When VI_1_A is set to output, the total number of inputs is nine. The video output can be either CVBS or luma.

Ten input terminals can be configured to support composite, S-video, and component YPbPr as listed in Table 2−12. User must follow this table properly for S-video and component applications because only the terminal configurations listed in Table 2−12 are supported.
