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. The structure of the exception vector table is shown in
figure 2.2.
The memory indirect (@@aa:8) and extended memory indirect (@@vec:7) addressing modes
are used in the JMP and JSR instructions. An 8-bit absolute address included in the instruction
code specifies a memory location. Execution branches to the contents of the memory location.
The stack structure of PC at a subroutine branch and that of PC and CCR at an exception
handling are shown in figure 2.3. The PC contents are saved or restored in 16-bit units.
