Additional 68HC11 Registers?

Don't quote me on this but:

With the HC11 series you can map internal RAM and registers to the same 4k chunk. They
are prioritised so that the internal registers have first priority and the internal RAM comes next.
Thus you would waste 64 odd bytes of RAM but would keep some address space for other stuff.

This goes for external memory too I think.

So it goes
	1) Internal registers
	2) Internal RAM / ROM	(don't quite know the priority of these two if any)
	3) External bus

That might or might not make any sense.

Flame on.
