I/O recalibration can result in I/O glitches. If it is important to avoid recalibration-induced I/O glitches, the I/O can be optionally configured to opt-out of recalibration. In this configuration, the I/O will be auto-calibrated on power-on / DEVRST_N only. To configure an I/O to opt-out of recalibration, select the Use IO Calibration from the lane check box in the I/O editor GUI. This will force the I/O to use a latched version of the power-on / DEVRST_N auto-calibration value located in the I/O lane controller.Figure 2-30. I/O Editor: Use IO Calibration from the lane option
