TIMING AND CONTROL
Mode 0 (CCIR-656): Slave Option
Timing Register 0 TR0 = X X X X X 0 0 0
The ADV7177/ADV7178 are controlled by the start active video (SAV) and end active video (EAV) time codes in the pixel data. All
timing information is transmitted using a 4-byte synchronization pattern. A synchronization pattern is sent immediately before and after
each line during active picture and retrace. Mode 0 is illustrated in Figure 14. The HSYNC, FIELD/VSYNC, and BLANK (if not used)
pins should be tied high during this mode.

Mode 0 (Ccir-656): Master Option
Timing Register 0 TR0 = X X X X X 0 0 1
The ADV7177/ADV7178 generate H, V, and F signals required for the SAV and EAV time codes in the CCIR-656 standard. The H bit is
output on the HSYNC pin, the V bit is output on the BLANK pin, and the F bit is output on the FIELD/VSYNC pin. Mode 0 is illustrated
in Figure 15 (NTSC) and Figure 16 (PAL). The H, V, and F transitions relative to the video waveform are illustrated in Figure 17.
