Bank B-4: VI End
The ADC-8032B has a programmable Vertical Interval that allows you to set where the VI ends and
the first line of active video begins. Everything up to (but not including) the first line of active video
is considered part of the Vertical Interval and will be affected by this function. In 525-line mode,
signals in the vertical interval are passed without setup even if setup is enabled. The range in 525-line
mode is line 20 to 22.
Note
VI End is only available in NTSC. In PAL-B, PAL-M, and
PAL-N, VI End cannot be changed.
