5.1
As table 5.1 indicates, exception handling is caused by a reset, a trace, an address error, an
interrupt, a trap instruction, and an illegal instruction (general illegal instruction or slot illegal
instruction). Exception handling is prioritized as shown in table 5.1. If two or more exceptions
occur simultaneously, they are accepted and processed in order of priority. Exception sources, the
stack structure, and operation of the CPU vary depending on the interrupt control mode. For
details on the interrupt control mode, see section 6, Interrupt Controller.

Exception Handling Start Timing
Exception handling starts at the timing of low-to-high transition on
the RES pin, watchdog timer overflow, or input of an external
interrupt signal*
state when the RES pin is low.
Exception handling starts when an undefined code is executed.
Exception handling starts after execution of the current instruction or
exception handling when the trace (T) bit in EXR has been set to 1,
After an address error has occurred, exception handling starts on
completion of instruction execution.
When an interrupt request has occurred, exception handling starts
after execution of the current instruction or exception handling.*
Exception handling starts by execution of a sleep instruction
(SLEEP) when the SSBY bit in SBYCR has been cleared to 0 and
the SLPIE bit in SBYCR has been set to 1.
Exception handling starts by execution of a trap instruction
(TRAPA).
