Differences between HD64645 and HD64646
Figure 1 and Figure 2 show the relation between display data transfer period, when display data shift clock
CL2 changes, and display data latch clock CL1. Figure 1 shows the case without skew function and Figure
2 shows the case with skew function.
In Figure 1, high period between CL2 and CL1 of HD64645 overlap. HD64646 has no overlap like
HD64645, and except for this overlap, HD64646 is the same as HD64645 functionally.
Also for the skew function, phase relation between CL1 and CL2 changes. As Figure 2 shows, data transfer
period and CL1 high period of HD64646 never overlap with the skew function.
