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 2-1). For details of the exception vector table, see section 4, Exception
Handling.
The memory indirect addressing mode (@@aa:8) employed in the JMP and JSR instructions uses an 8-bit absolute
address included in the instruction code to specify a memory operand that contains a branch address. In advanced mode
the operand is a 32-bit longword operand, providing a 32-bit branch address. The upper 8 bits of these 32 bits are a
reserved area that is regarded as H'00. Branch addresses can be stored in the area from H'00000000 to H'000000FF. Note
that the first part of this range is also the exception vector table.
