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) goes active. Some
follow-on chips require the VS pin to only change state when
HS is high/low.
Table 106. VSEHE Function
VSEHE
Description
0 (default) 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).
PVS Polarity VS, Address 0x37 [5]
The polarity of the VS pin can be inverted using the PVS bit.
Table 107. PVS Function
PVS
Description
0 (default) VS active high.
1
VS active low.
PF Polarity FIELD, Address 0x37 [3]
The polarity of the FIELD pin can be inverted using the PF bit.
Table 108. PF Function
PF
Description
0 (default) FIELD active high.
1
FIELD active low.
