• Stack Structure
Note: * Supported only by the H8S/2268 Group.
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 is 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 first part of this range is also the exception vector table.
In advanced mode, when the program counter (PC) is pushed onto the stack in a subroutine
call, and the PC, condition-code register (CCR), and extended control register (EXR * ) are
pushed onto the stack in exception handling, they are stored as shown in figure 2.4. When
EXR * is invalid, it is not pushed onto the stack. For details, see section 4, Exception Handling.
SP
Notes: 1. When EXR is not used it is not stored on the stack.
2. SP when EXR is not used (The H8S/2264 Group SP always points here).
3. Ignored when returning.
4. Supported only by the H8S/2268 Group.
