4.1
4.1.1
As table 4.1 indicates, exception handling may be caused by a reset, interrupt, or trap instruction.
Exception handling is prioritized as shown in table 4.1. If two or more exceptions occur
simultaneously, they are accepted and processed in priority order. Trap instruction exceptions are
accepted at all times in the program execution state.

Low
4.1.2
Exceptions originate from various sources. Trap instructions and interrupts are handled as follows.
1. The program counter (PC) and condition code register (CCR) are pushed onto the stack.
2. The CCR interrupt mask bit is set to 1.
3. A vector address corresponding to the exception source is generated, and program execution
Note: For a reset exception, steps 2 and 3 above are carried out.
starts from that address.
