• 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.
