112 Control Disables the core from inserting the InfoFrame packet.
  • 1: The core does not insert info_avi[111:0]. The AVI InfoFrame packet on the Auxiliary Data Port passes through.
  • 0: The core inserts info_avi[111:0] when there is a non-zero bit. The core sends default values when all bits are zero. The core filters the AVI InfoFrame packet on the Auxiliary Data Port.
–

By default, set the AVI version to version 2. If the value of info_avi[30:28] (EC2, EC1, EC0) is 3’b111, set the AVI version to version 4. If the value of info_avi[39] is 1’b1 (VIC >= 128) or info_avi[15] (Y2) is set to 1, set the AVI version to version 3.
