■
Dynamic reconfiguration duration is the number of cycles the busy signal is asserted
when the dynamic reconfiguration controller performs write transactions, read
transactions, or offset cancellation of the receiver channels.
PMA Controls Reconfiguration Duration
The following section contains an estimate of the number of reconfig_clk clock
cycles the busy signal is asserted during PMA controls reconfiguration using
Method 1, Method 2, or Method 3. For more information, refer to
Reconfiguring PMA Controls” on page 5–13

Enable self recovery option—When you select this option, the controller
automatically recovers if the operation did not complete within the expected time.
The error signal is driven high whenever the controller performs a self recovery.
