I don't program with the BIOS, so what I say may be slightly off for
your implementation. The stack memory has nothing special about it. You
can access it for reading or writing just like any other ram that is
accessible to your program. Obviously writing to it can easily corrupt
your program. The DSP does not have any level of protected memory.
Last year I wrote a routine that would overwrite most of the unused
space in the stack with a known pattern and then later count how much of
the stack space still had that known pattern. It was useful in finding
out how much of the stack I was using between a set of calls. It was
dangerous in that interrupt service routines also use the stack, and so
should be used with care.
