5.2.8. AFI and CSR Interfaces

The AFI interface provides communication between the controller and the physical layer logic (PHY). The CSR interface provides communication with your system’s internal control status registers.

For more information about AFI signals, refer to AFI 3.0 Specification in the Functional Description - UniPHY chapter.

Note: Unaligned reads and writes on the AFI interface are not supported.
