• 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 8 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.
