Rising edge of XRV input and decoder V123 is vertical reference
Falling edge of XRV input and decoder V123 is vertical reference
XRV is a V-sync or V gate signal
XRV is a frame sync, V pulses are generated internally on both edges of
FS input
X port field ID is state of XRH at reference edge on XRV (defined by
XFDV)
Field ID (decoder and X port field ID) is inverted
Reference edge for field detection is falling edge of XRV
Reference edge for field detection is rising edge of XRV
