I am facing problem while porting a project from S12DG to S12G micro and not able to correlate the address used between the projects linker .prm files.


In S12G linker prm file I have a section PAGE 8 defined as mentioned below,

ROM_PAGE08 = READ_ONLY 0x00088000 TO 0x0008BFFF;

But in S12DG linker prm file the same PAGE 0x8 is defined as section mentioned below,

PAGE38 = READ_ONLY 0x388000 TO 0x38BFFF;


So, I am not able to understand why it is mentioned PAGE 0x38 instead of PAGE 0x8?


I want to know how the local address is resolved from the Global address or alternative addressing in S12DG micro.


Thanks in advance,
