Advanced Mode

• Address Space
Linear access to a 16-Mbyte maximum address space is provided.
• 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 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 units of 32 bits. In each 32 bits, the upper 8 bits are ignored and a branch address is
stored in the lower 24 bits (figure 2.3). For details of the exception vector table, see section 4,
Exception Handling.
