Description
This bit is used to set up the output to interlaced or noninterlaced mode. Power-down mode
is relevant only when the part is in composite video mode.
These bits control the fields on which closed captioning data is displayed; closed captioning
information can be displayed on an odd field, even field, or both fields.
These bits can be used to power down the DACs. Power-down can be used to reduce the
power consumption of the ADV7174/ADV7179 if any of the DACs are not required in the
application.
A Logic 1 must be written to this register.
This bit can be used to generate and output an internal color bar test pattern. The color bar
configuration is 100/7.5/75/7.5 for NTSC and 100/0/75/0 for PAL. It is important to note that
when color bars are enabled, the ADV7174/ADV7179 is configured in a master timing mode.
