(r) : The status of polarity, present and static level for HSYNC and VSYNC.
CVpre = 1
→
The extracted CVSYNC is present.
= 0
→
The extracted CVSYNC is not present.
Hpol
= 1
→
HSYNC input is positive polarity.
= 0
→
HSYNC input is negative polarity.
Vpol
= 1
→
VSYNC (CVSYNC) is positive polarity.
= 0
→
VSYNC (CVSYNC) is negative polarity.
Hpre
= 1
→
HSYNC input is present.
= 0
→
HSYNC input is not present.
Vpre
= 1
→
VSYNC input is present.
= 0
→
VSYNC input is not present.
Hoff*
= 1
→

= 0
→
Off level of HSYNC input is low.
Voff*
= 1
→
Off level of VSYNC input is high.
= 0
→

*Hoff and Voff are valid when Hpre=0 or Vpre=0.
HCNTH
(r) :
H-Freq counter's high bits.
Hovf
= 1

= 1,0
→
Selects VSYNC as the polarity, freq and VBLANK source.
= 0,0
→
Disables composite function.
= 0,1
→
H/W automatically switches to CVSYNC when CVpre=1 and VSpre=0.
NoHins = 1
→
HBLANK has no insert pulse in composite mode.
= 0
→
