Can I perform back to back writes to the Intel® Stratix® 10 and Intel Agilex® E-Tile Native PHY RS-FEC registers?


Yes, you can perform back to back writes to the Intel Stratix 10 and Intel Agilex E-Tile Native PHY RS-FEC registers.

The E-Tile Transceiver PHY User Guide states the following in chapter “9.5. RS-FEC Registers”.

“The delay between RS-FEC register reads should be at least10 μs.”

There is no such requirement for register writes.


This information will be added to a future version of the Intel E-Tile Transceiver PHY User Guide.
