7.5.2
The hsync regeneration reproduces a regular hsync, e.g.
in case of equalizing pulses or an absent hsync during
vsync. The input selection is shown in Table 23.
Table 23 Hsync regeneration input selection
7.5.3
The source signals of the line-locked PLL are selected
according to Table 24 as either HSYNC and VSYNC from
the input pins or the composite sync decoder outputs
HS_CS and VS_CS.

The output selection for input interface and mode
detection allows to choose between the input signals
HSYNC and VSYNC, composite sync decoder outputs
HS_CS and VS_CS. The regenerated hsync HS_REGEN
can be selected as source (see Tables 25 and 26).
