• Address space

Linear access to a maximum address space of 16 Mbytes is possible.

• Extended registers (En)

The extended registers (E0 to E7) can be used as 16-bit registers. They can also be used as the

upper 16-bit segments of 32-bit registers or address registers.

• Instruction set

All instructions and addressing modes can be used.

• Exception vector table and memory indirect branch addresses

In advanced mode, the top area starting at H'00000000 is allocated to the exception vector

table in 32-bit units. In each 32 bits, the upper eight bits are ignored and a branch address is

stored in the lower 24 bits (see figure 2.3). For details of the exception vector table, see section

4, Exception Handling.
