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 at the output of the decoder
reserved
