This bit specifies whether an odd or even field is starting when the leading edge of HSYNC
occurs within the FIELD Detect Window. It is ignored unless HSYNC and VSYNC are config-
ured as inputs.
0 = odd field
1 = even field
This bit is cascaded with Field Detect Window Size Low to form a 9-bit Field Detect Window Size
value. This bit is ignored unless HSYNC and VSYNC are configured as inputs.
The 8-bit registers PHINC 0–3 are cascaded together to form a 32-bit PHINC value. The
PHINC value is the phase increment value of the color subcarrier generation NCO. When the
BT.656 ancillary data is selected as the PHINC source, the PHINC registers may be read to
determine the last PHINC value loaded via the selected interface.
