Is this true? That all video-related registers in CVO all are write-only?

The VIP manual does state in a footnote to the CVO register table:

(1) The rows in the table are repeated in ascending order for each video mode. All of the ModeN registers are write only.

When the MegaCore function receives a
new control packet on the Avalon-ST Video input, it searches the mode registers for a mode that is valid and has a field width and height that matches the width and height in the control packet.
