In addition to the 50/60 Hz and the 100/120 Hz Interlaced
display timing modes, the SAA567x; SAA569x also
supports basic Progressive Scan mode and Progressive
Scan with Interlace mode. Table 26 shows all the groups
of the display options that are supported.
Remark: The DISP FIELD bit (Status MMR) is derived
from the horizontal and vertical sync signals, it must not be
confused with the ACQ FIELD bit (Configuration MMR),
which is derived from the selected CVBS source.
Figures 26, 27, 28 and 29 show the DISP FIELD bit for the
various horizontal and vertical combinations.
