ADV7850 VDP Interrupt Generation

10.7.5
The ADV7850 generates a VBI data interrupt when the VBI data is received and when the line counter reaches a predetermined value.
This ensures that only one VBI data interrupt can occur once per field, regardless of which lines the VBI data is on, and regardless if the
VBI data is on concurrent lines or not. The interrupt is not generated if no VBI data was detected during the VBI region of that field. The
VBI interrupt is transmitted on the INT3 pin.
