Trying to learn how to initialize the SP register in assembly code. The linker parameter file can define STACKTOP but I can't see how to pass that to an LDS #LABEL in the assembler code. Have been looking for the C startup code INIT_SP_FROM_STARTUP_DESC(); to see how it is done there but can't find it.

Can anybody tell me where to find that code?

Cheers.

Look at file hidef.h in installation \lib\HC08c\include directory. the macro INIT_SP_FROM_STARTUP_DESC() is defined there.
