Allow semantic to parse only current buffer

Question

When editing a C file in emacs with semantic-mode, Is there a way to prevent semantic to recursively parse included files, and only allow it to parse the current buffer? I like some functionalities of semantic that only require parsing the current buffer (highlighting...), while I use rtags for navigation. I do not want to turn semantic off, but since parsing is extremely slow and blocks emacs, I would like to avoid it.
