Section 2 CPU
2.2
The H8S/2000 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. The mode is selected by the mode pins.
2.2.1
In normal mode, the exception vector table and stack have the same structure as the H8/300 CPU.
• Address Space
• Extended Registers (En)
• Instruction Set
• Exception Vector Table and Memory Indirect Branch Addresses
• Stack Structure
Note: Normal mode is not available in this LSI.

Linear access is provided to a maximum address space of 64 kbytes.
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) or
post-increment (@Rn+) 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.
In normal mode the top area starting at H'0000 is allocated to the exception vector table. One
branch address is stored per 16 bits. Figure 2.1 shows the structure of the exception vector
table in normal mode. For details of the exception vector table, see section 4, Exception
Handling.
The memory indirect addressing mode (@@aa:8) employed in the JMP and JSR instructions
uses an 8-bit absolute address included in the instruction code to specify a memory operand
that contains a branch address. In normal mode the operand is a 16-bit word operand,
providing a 16-bit branch address. Branch addresses can be stored in the top area from H'0000
to H'00FF. Note that this area is also used for the exception vector table.
In normal mode, when the program counter (PC) is pushed onto the stack in a subroutine call,
and the PC, condition-code register (CCR) and extended control register (EXR) are pushed
onto the stack in exception handling, they are stored as shown in figure 2.2. EXR is not pushed
onto the stack in interrupt control mode 0. For details, see section 4, Exception Handling.
