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 2-5. When
EXR is invalid, it is not pushed onto the stack. For details, see section 4, Exception Handling.
