Related Pins :
A. Video-in interface :
- VIN[0:7] (in/out) :
During normal mode, this bus
inputs
8-bit digital components of YCbCr 4:2:2 video-in data from
external
video controller (ex. TV decoder or MPEG decoder).
During test mode, this bus
outputs
8-bit digital components of YCbCr 4:2:2 video-out generated by
internal
video accelerator (VA).
- HSI (input) :
Horizontal Sync of video-in frames. The content of VAconf[] determines the polarity of this signal.
- VSI (input) :
Vertical Sync of video-in frames. The content of VAconf[] determines the polarity of this signal.
