2.3
Figure 2.5 shows a memory map of the H8S/2600 CPU. The H8S/2600 CPU provides linear
access to a maximum 64-kbyte address space in normal mode, and a maximum 16-Mbyte
(architecturally 4-Gbyte) address space in advanced mode. The usable modes and address spaces
differ depending on the product. For details on each product, refer to section 3, MCU Operating
Modes.
Note: Normal mode is not available in this LSI.
