333 Support can be enabled for different varieties of ROM monitor.
334 This support changes various eCos semantics such as the encoding
335 of diagnostic output, or the overriding of hardware interrupt
337 Firstly there is \"Generic\" support which prevents the HAL
338 from overriding the hardware vectors that it does not use, to
339 instead allow an installed ROM monitor to handle them. This is
340 the most basic support which is likely to be common to most
341 implementations of ROM monitor.
342 \"GDB_stubs\" provides support when GDB stubs are included in
343 the ROM monitor or boot ROM."
