Parameter
Typical
Value
Remarks
HPOL1
1
0 or 1. HSYNC Polarity
- Changing this value will increase margin at the left of the image
- Choose the value which produces the widest margin, and then
adjust with XDim1
VPOL1
1
0 or 1. VSYNC Polarity
Captured images will not be rectangular if incorrect value is chosen
XCLAMPPOL1
-1
-1=Internal, 0= Negative, or 1= Positive.
XCOASTPOL1
1
-1=Internal, 0= Negative, or 1= Positive.
PreCoast1
0
0 to 255. Number of clock synchronization pulses to skip prior to
COAST signal
PostCoast1
0
0 to 255. Number of clock synchronization pulses to skip after COAST
signal
SyncThreshold1
0 to 255. For composite signals only, used to differentiate a VSYNC
from a HSYNC
VCO1

Must be present and must be same value as in [CLOCK] section
CPmp1
6
Must be present and must be same value as in [CLOCK] section
N1
0
Must be present and must be same value as in [CLOCK] section
