passing pointers from C to assembler

Bruce Williamson

I want to pass a generic pointer from C to an assembly language function. Where can I find what the value in R3 means?

Thanks.

    See the compiler manual, Advanced Programming / Data Storage Formats / Generic and Far Pointers. Interfacing C to Assembler / Function Parameters would also be interesting.

    There's also a chart in the comments for XBANKING.A51 and L51_BANK.A51, which can be found in the lib directory of your Keil installation.
