7.1.6. Sink Auxiliary Data Port
The auxiliary port is attached to external memory. This port allows you to write packets to memory for use outside the HDMI core.
The core calculates the address for the data port using the header byte of the received packet. The core writes packet types 0–15 into a contiguous memory region.
Figure 35. Typical Application of AUX Packet Register InterfaceThe following figure shows a typical application of the auxiliary data port.
Memory Start Address | Packet Name |
