122 Control Disables the core from inserting the InfoFrame packet.
  • 1: The core does not insert info_avi[120:0]. The AVI InfoFrame packet on the Auxiliary Data Port passes through.
  • 0: The core inserts info_avi[120:0] 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.
