You should have an extended memory word to address all of memory, right?
Since this is a 16 bit Forth implementation, it is understandable that it can only address 64K words. However, we should be able to address all of the memory for data in the processor.
I haven't started using FlashForth yet, so my comments are not based on knowledge of FlashForth.

By design FlashForth can only address 64 Kbytes of memory.
FF maps flash, ram and eeprom into one 16-bit address space.
@ and ! can then be used with all types of memory.
The free flash should be about 45 Kbytes on chips that have 8 K ram and
4 K eeprom.
The FF kernel size is 8,5 Kbytes.
The mega1284 has 16 K of ram so only 36 K is left as free flash memory.
