(1) The inactive going edge of the V123 signal indicates whether the field is odd or even. If HREF is active during
the falling edge of V123, the field is ODD (field 1). If HREF is inactive during the falling edge of V123, the field
is EVEN. The specific position of the slope is dependent on the internal processing delay and may change a
few clock cycles from version to version.
The control signals listed above are available on pins RTS0, RTS1, XRH and XRV according to the following table:
