7.2.2 Internal assignment
The TDA9989 can accept any of the following video input modes (see
The TDA9989 can be set to latch data at either rising or falling edge, or both.
The aim of the video input processor is to internally map the incoming data to the
corresponding mode, which can be handled by the video processing. The internal signal
named VP[23:0] is assigned depending on the input mode as defined below.
