Hi,

I have a question about HSYNC and VSYNC internal pull state of DM6446.

The following documents, these pins have been described as IPD.

DM6446 Datasheet(SPRS283H)
[Table 2-20. VPBE Terminal Functions]

but, the description of the following table, these pins have an internal pullup (IPU).

DM6446 Datasheet(SPRS283H)
[Table 6-9. Switching Characteristics Over Recommended Operating Conditions During Reset]

Which state is correct?

Best regards,

Hello H.U,

The HSYNC and VSYNC pins are having internal pull-down. The Table 2-20 in the datasheet is correct for pull status. In the Table 6-9, the IPU and IPD are swapped for the z group pins. I hope it will be corrected in the next version.

Regards,
Senthil
