7.36 CUSTOMIZING PACKET/INFOFRAME STORAGE REGISTERS

The packet type value of each set of packet and InfoFrame registers in the InfoFrame Map is programmable. This allows the user to
configure the ADV7850 to store the payload data of any packet and InfoFrames sent by the transmitter connected on the selected HDMI
port.
Note: Writing to any of the nine following packet ID registers also clears the corresponding raw InfoFrame/packet detection bit. For
example, writing 0x82, or any other value, to avi_packet_id clears avi_info_raw.
