  5.    Information:
  6.        The attribute 'Name' is meant for register names from datasheets, debug messages or manually defined in upper case [A-Z0-9_]. e.g. "SDBUFCTR"
  7.            (this data will be generated into a header file, so really pick uppercase C-like names without spaces)
  8.        The attribute 'Text' is meant for the HUMAN READABLE form of what the register does. e.g. "Status Register" ro "Unknown"
  9.        The attribute 'Description' is meant for a descrption or notes related to this register.
  10.        Add a '?' suffix to mark the Name/Text as guessed/supposed.
