2.4.4.4.6. How to Disable ODI

After ODI is complete, disable ODI with the following procedure:
  1. Set register 0x168[0] to 0x0.
  2. Set register 0x158[5] to 0x0 to disable serial bit checker control.
  3. If the RX adaptation mode is set to manual30, set 0x148[0] to 0x0 to hold the adaptation in reset and save power.
  4. If the device is H-tile production and you want to enable background calibration, set 0x542[0] to 0x1.
Note: The ODI circuit performance can degrade over time if you do not enable the ODI circuit full time. If you need to run ODI again, refer to the Preserving ODI Performance section.
30 To determine RX adaptation mode, read 0x161[5]. RX adaptation is in manual mode when 0x161[5] = 1.
