In ADV7619 Hardware User Guide, we found following description:
This bit allows the user to tristate the output driver of pixel outputs. Upon setting TRI_PIX, the pixel output P[35:0] is tristated.
TRI_PIX , IO, Address 0x15
A control to tristate the pixel data on the pixel pins, P[47:0].
We have one design need two ADV7619 with parallel connections to act as a 4:1 HDMI receiver, can TRI_PIX tristate all of the P[ 47:0] pins?
