Vertical timing
During vertical synchronization, as in horizontal synchronization, the counter is reset when DVD falls and
incremented when HD falls (see Fig 12.1-4 and Fig 12.1-5).
Set the Field 1 and Field 2 blanking periods separately for each TV system in the blanking start parameters in
Table 12.1-6.
