Linear access is provided to a 16-Mbyte maximum address space.
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.
All instructions and addressing modes can be used.
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 5, Exception
Handling.
