-/* These define the size of main memory for the simulator.

- Note the size of main memory for the H8/300H is only 256k. Keeping it
- small makes the simulator run much faster and consume less memory.
-
- The linker knows about the limited size of the simulator's main memory
- on the H8/300H (via the h8300h.sc linker script). So if you change
- H8300H_MSIZE, be sure to fix the linker script too.
-
- Also note that there's a separate "eightbit" area aside from main
- memory. For simplicity, the simulator assumes any data memory reference
- outside of main memory refers to the eightbit area (in theory, this
- can only happen when simulating H8/300H programs). We make no attempt
