Figure 2.4 Stack Structure In Advanced Mode - Renesas H8S Series Hardware Manual

• Stack Structure
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.
3. Ignored when returning.
