6.2. Interacting with the Reconfiguration Interface
A transmit PLL instance has a maximum of one reconfiguration interface. Unlike PLL instances, 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 all channels to perform dynamic reconfiguration.
Avalon-MM masters interact with the reconfiguration interface by performing Avalon read and write operations to initiate dynamic reconfiguration of specific transceiver parameters. All read and write operations must comply with Avalon-MM specifications.
The user-accessible Avalon-MM reconfiguration interface and PreSICE Avalon-MM interface share a single internal configuration bus. This bus is arbitrated to get access to the Avalon-MM interface of the channel or PLL. Refer to the Arbitration section for more details about requesting access to and returning control of the internal configuration bus from PreSICE.
