4.1
4.1.1
As table 4.1 indicates, exception handling may be caused by a reset, trap instruction, or interrupt.
Exception handling is prioritized as shown in table 4.1. If two or more exceptions occur
simultaneously, they are accepted and processed in order of priority. Trap instruction exceptions
are accepted at all times in the program execution state.
Exception handling sources, the stack structure, and the operation of the CPU vary depending on
the interrupt control mode set by the INTM0 and INTM1 bits of SYSCR.
Table 4.1
Priority
High
Low
Notes: 1. Traces are enabled only in interrupt control mode 2. Trace exception handling is not
2. Interrupt detection is not performed on completion of ANDC, ORC, XORC, or LDC
3. Trap instruction exception handling requests are accepted at all times in the program

Start of Exception Handling
Starts immediately after a low-to-high transition at the
RES pin, or when the watchdog timer overflows
Starts when execution of the current instruction or
