RW Senser,

I was playing around with the memory map that cc1b generates.
"#pragma rambank -" sets the base of the ram allocated for globals and locals
to the Mapped Ram ($00-$0F) (aka SharedRam)
"#pragma rambank 1" sets the base of the ram allocated for globals and locals
to rambank 1 ($10-$1F), etc for 2-15
"#pragma rambank 0" sets the base of the ram allocated for globals and locals
to rambank 0 (SX48/52 only, $100-$10F)

My libraries use only locals and should therefor not be restricted in which library comes
first, but that will require a #pragma rambank 1 in the C main file (so no mapped ram
is used for locals).
I also noted cc1b always allocates rambank 7 ($70-$7F) and I have not yet found
out to what (data stack perhaps?).

There is also "#pragma rambase xx" but I am not quite sure about the difference between
rambank and rambase. I think we should first have a clear understanding how cc1b
deals exactly with globals and locals. I use the cc5x manual as guideline but cc1b
may differ slightly in some cases.

regards peter
