Hi,
At first, the SMALL compile memory model is used, which of course the internal data is used.
However since the memory space is not enough for current project development; the LARGE compile memory model is used.
In order to enhance the code speed as much as possible, the memory type on the passing parameter is used; however the external memory address is still used (here @DPTR register is used). Of course, the memory type does have effect on the pointer parameter!
I'd like to know whether the un-pointer parameters' meomry addresses can only be determined by the compile meomry model and cannot be overriden by the meomry type specifier!
