<sect>Special segments<p>
The builtin config files do contain segments that have a special meaning for
the compiler and the libraries that come with it. If you replace the builtin
config files, you will need the following information.
<sect1>INIT<p>
The INIT segment is used for initialization code that may be reused once
executation reaches main() - provided that the program runs in RAM. You
may for example add the INIT segment to the heap in really memory
constrained systems.
<sect1>LOWCODE<p>
For the LOWCODE segment, it is guaranteed that it won't be banked out, so it
is reachable at any time by interrupt handlers or similar.
<sect1>STARTUP<p>
This segment contains the startup code which initializes the C software stack
and the libraries. It is placed in its own segment because it needs to be
loaded at the lowest possible program address on several platforms.
<sect1>HEAP<p>
This segment defines the location of the memory heap used by the malloc
routine.
