field state directly controlled via FSEL
automatic field detection; recommended setting
50 Hz, 625 lines
60 Hz, 525 lines
ODD/EVEN signal toggles only with interlaced source
ODD/EVEN signal toggles fieldwise even if source is
non-interlaced
TV mode, recommended for poor quality TV signals only; do
not use for new applications
VTR mode, recommended if a deflection control circuit is
directly connected to the SAA7108E; SAA7109E
reserved
fast locking mode; recommended setting
PLL closed
PLL open; horizontal frequency fixed
normal mode; recommended setting
fast mode, applicable for stable sources only; automatic field
detection (AUFD) must be disabled
