Instruction set
All instructions and addressing modes can be used.
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 32-bit units. In each 32 bits, the upper 8 bits are ignored and a branch address is stored
in the lower 24 bits (see figure 2.3). For details on 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 top area of this range is also used for the exception vector table.
Stack structure
In advanced mode, when the program counter (PC) is pushed onto the stack in a subroutine
call, and the PC and condition-code register (CCR) are pushed onto the stack in exception
handling, they are stored as shown in figure 2.4. The extended control register (EXR) is not
pushed onto the stack. For details, see section 4, Exception Handling.
