After clearing CCIF to launch the Read Resource command, eight consecutive bytes are
read from the selected resource at the provided relative address and stored in the FCCOB
register. The CCIF flag will set after the Read Resource operation has completed. The
Read Resource command exits with an access error if an invalid resource code is
provided or if the address for the applicable area is out-of-range.
