• Stack Structure
Note: Normal mode is not available in this LSI.
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. EXR is not pushed onto the
stack in interrupt control mode 0. For details, see section 4, Exception Handling.
SP
Notes:
Figure 2.1 Exception-Handling Vector Table (Normal Mode)
1. When EXR is not used, it is not stored on the stack.
2. SP when EXR is not used.
3. lgnored when returning.
