Section 1 CPU
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 1.4).
The exception vector table differs depending on the microcontroller. Refer to the relevant
microcontroller hardware manual for further information.
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 top area from H'00000000 to H'000000FF. Note that
this area is also used for the exception vector table.
