Arria 10/Cyclone 10 Transceiver

I am using the "Transceiver Native PHY Intel Arria 10/Cyclone 10 FPGA IP" and set "adaptation enabled" in the DFE mode.

In this mode, will the DFE tap be always calibrated automatically or do we need to write some registers to initialize the calibration each time?

If we need to write to some register, could you please send us a reference?
