7.2. Interacting with the Dynamic Reconfiguration Interface
Each transceiver channel contains a reconfiguration interface shared with the PMA
Interface (PMAIF), PMA and Embedded Multi-die Interconnect Bridge (EMIB).
Additionally, there are six reconfiguration interfaces per E-Tile allowing access to the
six RS-FEC blocks.
The reconfiguration interface provides direct access to the programmable space of
each channel. Communication with the channel reconfiguration interface requires an
AVMM master. Because each channel has its own dedicated AVMM interface, you can
dynamically reconfigure channels either concurrently or sequentially, depending on
how the AVMM master is connected to the AVMM reconfiguration interface.

Note:
1. The Native PHY IP core, user reconfiguration logic (AVMM master), interfaces
with the hard registers and EMIB using the AVMM reconfiguration interface.
A Native PHY IP core instance can specify multiple channels. You can use a dedicated
reconfiguration interface for each channel or share a single reconfiguration interface
across multiple channels to perform dynamic reconfiguration.
