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-handling
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-handling vector
table, see section 4, Exception Handling.
