6.8.1. Disabling Background Calibration
H-tile Ethernet Hard IP core implements the Auto Adaptation triggering for RX PMA CTLE/DFE mode.
For Intel® Stratix® 10 H-tile production devices, disable the background calibration first prior to accessing the transceiver core reconfiguration register. The Intel® Stratix® 10 H-tile ES devices do not have background calibration.
In Intel® Quartus® Prime software version 19.2 onwards, use the following steps to access the transceiver core reconfiguration registers:
- Write 0x0 into register 0x542[0] of the transceiver control and status registers using the transceiver reconfiguration Avalon® -MM interface to disable background calibration.
- Access the transceiver register, for example, to perform the transceiver reconfiguration.
- Once completed, write 0x1 into register 0x542[0] of the transceiver control and status registers using the transceiver reconfiguration Avalon® -MM interface to enable background calibration.
