6.6.2.2. EDID Interface

You can use the Avalon® memory-mapped EDID interface to access an on-chip memory region containing the sink’s EDID data. The AUX sink controller reads and writes to this memory region according to traffic on the AUX channel.

The Avalon® memory-mapped interface uses an 8-bit address with an 8-bit data bus. The interface assumes a read latency of 1.

Note: The IP core does not instantiate this interface if your design uses a controller to control the sink; for instance, when you turn on the Enable GPU control parameter.
