Clamp pulse selection for RGB and YUV signals
Table 52
Selection of secondary audio channel
Note
1.
Selection between AMint and AMext must be done by
digital video processor.
Table 53
Secondary audio channel mode
Note
1.
Mono is (L + R)/2; when AM is selected in Table 52,
mono is AMint for SEA[2:0] = 000 and AMext for
SEA[2:0] = 111. A more comprehensive table can be
found in the application note.

Selection of primary audio channel
Note
1.
Selection between AMint and AMext must be done by
digital video processor.
