2.2
The H8SX CPU has four operating modes: normal, middle, advanced and maximum modes. For
details on mode settings, see section 3.1, Operating Mode Selection.
2.2.1
The exception vector table and stack have the same structure as in the H8/300 CPU.
Note: Normal mode is not supported in this LSI.
• Address Space
• Extended Registers (En)
• Instruction Set
The maximum address space of 64 kbytes can be accessed.
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 the extended register 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 Rn is referenced in the register indirect addressing mode with
pre-/post-increment or pre-/post-decrement and a carry or borrow occurs, however, the value in
the corresponding extended register En will be affected.)
All instructions and addressing modes can be used. Only the lower 16 bits of effective
addresses (EA) are valid.
