-/* Memory Model
- The HEAP starts at the end of the DATA section and grows upward.
-
- The STACK starts at the end of the RAM and grows downward.
-
- The HEAP and stack STACK are only checked at compile time:
- (DATA_SIZE + HEAP_SIZE + STACK_SIZE) < RAM_SIZE
-
- This is just a check for the bare minimum for the Heap+Stack area before
- aborting compilation, it is not the run time limit:
- Heap_Size + Stack_Size = 0x200 + 0x400 = 0x600
