Hi, it is broken link as the section is not present in the manual. I think it is not supposed to be there at all and the link should be removed. I will report is as a documentation error. Thanks for highlighting of the issue.
If you want to see which code is was supposed to point to, you may take a look to different device manual, specifically section 24.7.2:
