Notes: 1. Memory with interface such as SRAM or ROM.
2. Use external pin to specify memory bus width.
3. Use register to specify memory bus width.
4. With synchronous DRAM interfaces, bus width must be 16 or 32 bits.
5. With PCMCIA interface, bus width must be 8 or 16 bits.
6. Do not access the reserved area. If the reserved area is accessed, correct operation
cannot be guaranteed.
7. When the control register in area 1 is not used for address translation by the MMU, set
the first three bits of the logical address to 101 for allocation to the P2 space.
