"What does Symbol width mean?"

I'm not sure about the concept of Symbol width used in "Avalon-MM Pipeline Bridge" or "Clock Crossing Bridge." Could you please provide more information or clarify your question?

When the term "symbol" is mentioned, it doesn't seem to specifically refer to BPSK or QPSK.

The datasheet mentions "Width of a single symbol in bits," which is quite confusing.

it's mean..

Case 1:
> Data Width: 16
> Symbol Width: 16
=> In one Read operation, it reads/writes the full Data width.

Case 2:
> Data Width: 16
> Symbol Width: 8
=> It requires two Read operations, and in each Read, it reads/writes 8 bits.

and what's different address units (Symbols, WORDS)
