Section 2 CPU
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.
