VS and FIELD Configuration
The following controls allow the user to configure the behavior
of the VS and FIELD output pins, as well as the generation of
embedded AV codes:

NEWAVMODE New AV Mode, Address 0x31, [4]
Table 102. NEWAVMODE Function
NEWAVMODE
Description
0
EAV/SAV codes generated to suit ADI
encoders. No adjustments possible.
1*
Enable Manual Position of VSYNC, Field, and
AV codes using 0x34 to 0x37 and 0xE5 to 0xEA.
Default register settings are CCIR656
compliant; see Figure 21 for NTSC and
Figure 26 for PAL. For recommended manual
user settings, see Table 110 and Figure 22 for
NTSC; see Table 123 and Figure 27 for PAL.
*Default value.
HVSTIM Horizontal VS Timing (SDP), Address 0x31, [3]
The HVSTIM bit allows the user to select where the VS signal is
being asserted within a line of video. Some interface circuitry
may require VS to go low while HS is low.
Table 103. HVSTIM Function
HVSTIM
Description
0*
Start of line relative to HSE.
1
Start of line relative to HSB.
*Default value.
VSBHO VS Begin Horizontal Position Odd (SDP),
Address 0x32, [7]
The VSBHO and VSBHE bits select the position within a line at
which the VS pin (not the bit in the AV code) goes active. Some
follow-on chips require the VS pin to only change state when
HS is high/low.
Table 104. VSBHO Function
VSBHO
Description
0*
VS pin goes high at the middle of a line of video
(odd field).
1
VS pin changes state at the start of a line (odd
field).
*Default value.
VSBHE VS Begin Horizontal Position Even (SDP),
Address 0x32, [6]
The VSBHO and VSBHE bits select the position within a line at
which the VS pin (not the bit in the AV code) goes active. Some
follow-on chips require the VS pin to only change state when
HS is high/low.
Table 105. VSBHE Function
VSBHE
Description
0*
VS pin goes high at the middle of a line of video
(even field).
1
VS pin changes state at the start of a line (even field).
*Default value.
VSEHO VS End Horizontal Position Odd (SDP),
Address 0x33, [7]
The VSEHO and VSEHE bits select the position within a line at
which the VS pin (not the bit in the AV code) goes active. Some
follow-on chips require the VS pin to only change state when
HS is high/low.
Table 106. VSEHO Function
VSEHO
Description
0*
VS pin goes low (inactive) at the middle of a line of
video (odd field).
1
VS pin changes state at the start of a line (odd field).
*Default value.
