timing requirements for DCS DMA mode (figure 12 of the ADV212 datasheet)
does not specify the minimum RD input low pulse time. This information is
essential for using the ADV212 with this DMA mode.
First: I would not recommend using DCS mode. It's sole purpose was for working with a PC's PCI bus and I'm not aware that anyone has used it otherwise.
It's the time of the edges relative to the data that is important, RD pulse width is not specified but if you want a minimum it shouldn't be less than an MCK low time.
