VSEHE VS End Horizontal Position Even (SDP),
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) goes active. Some
follow-on chips require the VS pin to only change state when
HS is high/low.
Table 107. VSEHE Function
VSEHE Description
0*
VS pin goes low (inactive) 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.

PVS Polarity VS (SDP), Address 0x37, [5]
The polarity of the VS pin as it comes from the SDP block can
be inverted using the PVS bit.
Table 108. PVS Function
PVS
Description
0*
VS active high.
1
VS active low.
*Default value.
PF Polarity FIELD (SDP), Address 0x37, [3]
The polarity of the FIELD pin as it comes from the SDP block
can be inverted using the PF bit.
Table 109. PF Function
