7.9. Recommendations for PMA Dynamic Reconfiguration

Some PMA features that can be dynamically reconfigured, like the reference clock source, the TX and RX data rate require the PMA and digital blocks to be in the reset state. Intel recommends that you:

  • Hold the channel transmitter in digital reset and assert PMA attribute codes to disable the PMA TX during reconfiguration.
  • Hold the channel receiver in digital reset and assert PMA attribute codes to disable the CDR during reconfiguration.
