Is it required that all unused I/O pins be pulled down?
For example, must HDATA[31:16] be pulled down when using a 16-bit Host Interface?
Must VDATA[3:0] be pulled down when using 8-bit VDATA mode?
What about SCOMM pins?
What about HVF pins when using EAV/SAV mode?
I'm working on a design with multiple ADV212s and I want to avoid dozens of resistors if they're not really needed.
