Section 1 CPU
Exception Vector Table and Memory Indirect Branch Addresses: In normal mode the top area
starting at H'0000 is allocated to the exception vector table. One branch address is stored per
16 bits (figure 1.2). 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 normal mode the operand is a 16-bit word operand, providing a
16-bit branch address. Branch addresses can be stored in the top area from H'0000 to H'00FF.
Note that this area is also used for the exception vector table.
