VS and FIELD Configuration
The following controls allow the user to configure the behav-
ior of the VS and FIELD output pins, as well as to generate
embedded AV codes:
NEWAVMODE New AV Mode, Address 0x31[4]
When NEWAVMODE is 0, EAV/SAV codes are generated to
suit ADI encoders. No adjustments are possible.
Setting NEWAVMODE to 1 (default) enables the manual
position of the VSYNC, Field, and AV codes using
Registers 0x34 to 0x37 and Register 0xE5 to 0xEA. Default
register settings are CCIR656 compliant; see
and
see
for PAL.
HVSTIM Horizontal VS Timing, 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
can require VS to go low while HS is low.
When HVSTIM is 0 (default) the start of the line is relative
to HSE.
When HVSTIM is 1, the start of the line is relative to HSB.

VSBHO VS Begin Horizontal Position Odd, 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) becomes active.
Some follow-on chips require the VS pin to change state only
when HS is high/low.
When VSBHO is 0 (default), the VS pin goes high at the middle
of a line of video (odd field).
When VSBHO is 1, the VS pin changes state at the start of a line
(odd field).
VSBHE VS Begin Horizontal Position Even, 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) becomes active.
Some follow-on chips require the VS pin to change state only
when HS is high/low.
When VSBHE is 0 (default), the VS pin goes high at the middle
of a line of video (even field).
When VSBHE is 1, the VS pin changes state at the start of a line
(even field).
VSEHO VS End Horizontal Position Odd, 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) becomes active.
Some follow-on chips require the VS pin to change state only
when HS is high/low.
When VSEHO is 0, the VS pin goes low (inactive) at the middle
of a line of video (odd field).
When VSEHO is 1 (default), the VS pin changes state at the
start of a line (odd field).
VSEHE VS End Horizontal Position Even, Address 0x33[6]
The VSEHO and VSEHE bits select the position within a line at
which the VS pin (not the bit in the AV code) becomes active.
Some follow-on chips require the VS pin to change state only
when HS is high/low.
When VSEHE is 0 (default), the VS pin goes low (inactive) at
the middle of a line of video (even field).
When VSEHE is 1, the VS pin changes state at the start of a line
(even field).
PVS Polarity VS, Address 0x37[5]
The polarity of the VS pin can be inverted using the PVS bit.
When PVS is 0 (default), VS is active high. When PVS is 1, VS is
active low.
PF Polarity FIELD, Address 0x37[3]
The polarity of the FIELD pin can be inverted using the PF bit.
When PF is 0 (default), FIELD is active high. When PF is 1,
FIELD is active low.
