Reserved
= Reserved or unimplemented bits.
1. Port A, port B and data direction registers DDRA, DDRB are not in map in expanded and peripheral modes.
2. Port E and DDRE not in the map in peripheral and expanded modes with EME set.
3. Registers also not in map in peripheral mode.
4. Data read at these locations is undefined.
5. The FPOPEN bit is available only on the 0L05H and later mask sets. For previous masks, this bit is reserved.
6. Port K and DDRK not in the map in peripheral and expanded modes with EMK set.
7. MC68HC912DT128A only. Locations are unimplemented on the MC68HC912DG128A.
