4.1
As table 4.1 indicates, exception handling may be caused by a reset, trace * , 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 exception
handling requests are accepted at all times in program execution state.
Exception sources, the stack structure, and operation of the CPU vary depending on the interrupt
control mode set by the INTM0 and INTM1 bits in SYSCR.

Section 4 Exception Handling
Start of Exception Handling
Starts immediately after a low-to-high transition at the RES pin,
or when the watchdog timer overflows. The CPU enters the
reset state when the RES pin is low.
Starts when execution of the current instruction or exception
handling ends, if the trace (T) bit in the EXR is set to 1. Traces
are enabled only in interrupt control mode 2. Trace exception
handling is not executed after execution of an RTE instruction.
Starts when execution of the current instruction or exception
handling ends, if an interrupt request has been issued. Interrupt
detection is not performed on completion of ANDC, ORC,
XORC, or LDC instruction execution, or on completion of reset
exception handling.
Started by execution of a trap instruction (TRAPA). Trap
instruction exception handling requests are accepted at all times
in program execution state.
