I don't know where the word has come, and I can't find it in the TFP410
documentation. I guess the idea with the word was that the chip
"frames", i.e. packetizes, the incoming parallel data to DVI.
But I think it's better to remove the use of the word to avoid any
confusion. I'll make the change.

Hmm, yes, I think you are right.
