   8 Xstormy16 Function Attributes
   9 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  10
  11 These function attributes are supported by the Xstormy16 back end:
  12
  13 .. index:: interrupt function attribute, Xstormy16
  14
  15 .. xstormy16-fn-attr:: interrupt
  16
  17   Use this attribute to indicate
  18   that the specified function is an interrupt handler.  The compiler generates
  19   function entry and exit sequences suitable for use in an interrupt handler
  20   when this attribute is present.
