- /* The 68HC12 microcontroler has a memory bank switching system
- with a 16Kb window in the 64Kb address space. The extended memory
- is mapped in the 16Kb window (at 0x8000). The page register controls
- which 16Kb bank is mapped. The call/rtc instructions take care of
- bank switching in function calls/returns.
- For GNU Binutils to work, we consider there is a physical memory
- at 0..0x0ffff and a kind of virtual memory above that. Symbols
- in virtual memory have their addresses treated in a special way
- when disassembling and when linking.
- For the linker to work properly, we must always relocate the virtual
- memory as if it is mapped at 0x8000. When a 16-bit relocation is
- made in the virtual memory, we check that it does not cross the
- memory bank where it is used. This would involve a page change
- which would be wrong. The 24-bit relocation is for that and it
- treats the address as a physical address + page number.
