6.10. Native PHY IP or PLL IP Core Guided Reconfiguration Flow

Use the Native PHY IP core or PLL IP core guided reconfiguration flow to perform dynamic reconfiguration when you need to change multiple parameters or parameters in multiple addresses for the transceiver channel or PLL. You can use this flow to change data rates, change clock divider values, or switch from one PCS datapath to another. You must generate the required configuration files for the base and modified Transceiver Native PHY IP core or PLL IP core configurations.

The configuration files contain addresses and bit values of the corresponding configuration. Compare the differences between the base and modified configuration files. The differences between these files indicate the addresses and bit values that must change to switch from one configuration to another. Perform read-modify-writes for the bit values that are different from the base configuration to obtain the modified configuration.

To perform dynamic reconfiguration using the IP Guided Reconfiguration Flow:

  1. Perform the necessary steps from steps 1 to 7 in Steps to Perform Dynamic Reconfiguration.
  2. Perform a read-modify-write to all addresses and bit values that are different from the base configuration.
