2) Output modes
The “Video-CD” and “CD-G” modes can be supported
by both digital image and video data, with the mode
being switched by the CDGSWB pin input. When the
CDGSWB pin input is LOW, the CD-G mode is set, and
when HIGH, the Video-CD mode is set. Also, the
“NTSC”, “PAL”, and “PAL60” modes may be selected
as the output TV modes. The output TV mode is
switched using the NTB and PAL60 pin input. Setting
the NTB pin input to LOW sets the NTSC mode, and
setting it HIGH with the PAL60 pin also HIGH sets the
PAL mode. Setting the NTB pin HIGH and the PAL60
pin LOW, sets the PAL60 mode.

Also, INT pin input can be used to switch between
“interlace output” and “non-interlace output.”
Setting the input to LOW enables non-interlace output,
and setting it to HIGH enables interlace output. When
non-interlace output is used, the number of lines in one
field can be controlled using the ADDH pin. If the ADDH
pin is LOW, the number of lines in one field is set to the
number of interlace output lines minus 0.5 lines, and
when HIGH, the number of lines in one field is set to the
number of interlace output lines plus 0.5 lines.

3) Input formats
The digital data input format can be set as shown in the
table below, using the IM1 and IM0 pins. Both 24-bit
RGB (4: 4: 4) and 16-bit YUV (4: 2: 2) are supported. In
addition, digital RGB input can be output as analog
RGB output (RGB Through mode).
