Figure 2.6 Exception Vector Table (Maximum Modes)

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.

In maximum mode, an operand is a 32-bit (longword) operand, providing a 32-bit branch

address.

• Stack Structure

The stack structure of PC at a subroutine branch and that of PC and CCR at an exception

handling are shown in figure 2.7. The PC contents are saved or restored in 32-bit units. The

EXR contents are saved or restored regardless of whether or not EXR is in use.
