Active Area Control
Four registers HSTART (horizontal start), HEND (horizon-
tal end), VSTART (vertical start) and VEND (vertical end)
determine the active video area. The maximum active video
area is 768 by 288 pixels for a single field.
Video Format
This control determines the video format that is supported. In
general, the goal of the various video formats is to support
glueless interfaces to the wide variety of video formats periph-
eral components expect. This control is maintained by the
host processor. Table VII shows a synopsis of the supported
video formats. Definitions of each format can be found later
in this section. For Video Interface pins descriptions, see the
Pin Function Descriptions.

Clocks and Strobes
All video data, whether 1 or 2 “l(fā)anes” of video are used, are
synchronous to the video clock (VCLK). The rising edge of
VCLK is used to clock all data into the ADV601.
Synchronization and Blanking Pins
Three signals, which can be configured as inputs or outputs, are
used for video frame and field horizontal synchronization and
blanking. These signals are VSYNC, HSYNC, and FIELD.
VDATA Pins Functions With Differing Video Interface Formats
The functionality of the Video Interface pins depends on the
current video format. Table VIII defines how Video data pins
are used for the various formats.

NOTE
1
Italic font for an entry in this table indicates that the use of the pin is optional (i.e., bits per component greater than 8 ). Note that unused optional pins should be tied
through a resistor to ground. Also, N/C for an entry in this table indicates that the pin is never used for a particular video format. This nomenclature is consistent
with the Video Format Descriptions found later in this section. Note that Data0 is always the LSB for all formats.
