Address Space
The maximum address space of the H8/300H CPU is 16 Mbytes. The H8/3048B Group has
various operating modes (MCU modes), some providing a 1-Mbyte address space, the others
supporting the full 16 Mbytes.
Figure 2.2 shows the address ranges of the H8/3048B Group. For further details see section 3.6,
Memory Map in Each Operating Mode.
The 1-Mbyte operating modes use 20-bit addressing. The upper 4 bits of effective addresses are
ignored.
