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

Notes: 1.
(a) Subroutine Branch
2.
3.
When EXR is not used it is not stored on the stack.
SP when EXR is not used.
Ignored when returning.
