4.12.25 Video Display Vertical Interrupt Register (VDVINT)

The video display vertical interrupt register (VDVINT) controls the generation of vertical interrupts in field 1
and field 2.
An interrupt can be generated upon completion of the specified line in a field (when FLCOUNT = VINTn).
This allows the software to synchronize itself to the frame or field. The interrupt can be programmed to
occur in one, both, or no fields using the VIF1 and VIF2 bits.
The video display field bit register (VDVINT) is shown in
