4:2:2 Output Mode Select
This bit configures the output data in 4:2:2 mode. This mode
can be used to reduce the number of data lines used from 24 to
16 for applications using YPbPr graphics signals. A timing
diagram for this mode is shown in Figure 17. Recommended
input and output configurations are shown in Table 39. In
4:2:2 mode, the red and blue channels can be interchanged to
help satisfy board layout or timing requirements, but the green
channel must be configured for Y.

Hsync Detect
This bit is used to indicate when activity is detected on the
HSYNC input pin (Pin 79). If Hsync is held high or low, activity
is not detected.

Sync-on-Green Detect

sync-on-green input pin (Pin 64).

Note that if no sync signal is presented on the green video
input, normal video might still trigger activity.

Vsync Detect
This bit is used to indicate when activity is detected on the
Vsync input pin (Pin 80). If Vsync is held high or low, activity is
not detected.

Active Interface
This bit is used to indicate which interface should be active,
analog or digital. It checks for activity on the analog interface
and for activity on the digital interface, then determines which
should be active according to Table 44. Specifically, analog
interface detection is determined by OR’ing Bits 7, 6, and 5 in
this register. Digital interface detection is determined by Bit 4 in
this register. If both interfaces are detected, the user can
determine which has priority via Bit 1 in Register 0x0F. The
user can override this function via Bit 2 in Register 0x0F. If the
override bit is set to Logic 1, then this bit will be forced to the
same state as Bit 1 in Register 0x0F.

AHS Active Hsync
This bit indicates which Hsync input source is being used by
the PLL (Hsync input or sync-on-green). Bits 6 and 7 in
Register 0x15 determine which source is used. If both Hsync
and SOG are detected, the user can determine which has
priority via Bit 3 in Register 0x10. The user can override this
function via Bit 4 in Register 0x10. If the override bit is set to
Logic 1, then this bit will be forced to the same state as Bit 3 in
Register 0x10.
