CPU Operating Modes
Like the H8/300H CPU, 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
4-Gbyte total address space, of which up to 16 Mbytes can be used for program code and up to 4
Gbytes for data. The mode is selected with the mode pins of the microcontroller. For further
information, refer to the relevant microcontroller hardware manual.
CPU operating modes
(1) Normal Mode
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, as in the H8/300 CPU.
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 (R0 to R7) is used as an address register.
If the general register is referenced in the register indirect addressing mode with pre-decrement
(@–Rn) or post-increment (@Rn+) and a carry or borrow occurs, however, the value in the
corresponding extended register will be affected.
Instruction Set: All additional instructions and addressing modes not found in the H8/300 CPU
can be used. Only the lower 16 bits of effective addresses (EA) are valid.
