Section 2 CPU
2.2
The H8S/2600 CPU has two operating modes: normal and advanced. Normal mode * supports a
maximum 64-kbyte address space. Advanced mode supports a maximum 16-Mbyte total address
space (architecturally a maximum 16-Mbyte program area and a maximum of 4 Gbytes for
program and data areas combined). The mode is selected by the mode pins of the microcontroller.
Note: * Not available in the H8S/2626 Group or H8S/2623 Group.
(1) Normal Mode (Not Available in the H8S/2626 Group or H8S/2623 Group)
The exception vector table and stack have the same structure as in the H8/300 CPU.
Address Space: A maximum address space of 64 kbytes can be accessed.
Extended Registers (En): The extended registers (E0 to E7) can be used as 16-bit registers, or as
the upper 16-bit segments of 32-bit registers. When En is used as a 16-bit register it can contain
any value, even when the corresponding general register (Rn) is used as an address register. If the
general register is referenced in the register indirect addressing mode with pre-decrement (@–Rn)
