Section 4 Exception Handling
The on-chip supporting modules that can request interrupts are the watchdog timer (WDT), 16-bit
timer, 8-bit timer, serial communication interface (SCI), and A/D converter. Each interrupt source
has a separate vector address.
NMI is the highest-priority interrupt and is always accepted * . Interrupts are controlled by the
interrupt controller. The interrupt controller can assign interrupts other than NMI to two priority
levels, and arbitrate between simultaneous interrupts. Interrupt priorities are assigned in interrupt
priority registers A and B (IPRA and IPRB) in the interrupt controller.
For details on interrupts see section 5, Interrupt Controller.
Note: * In the versions with on-chip flash memory, NMI input is sometimes disabled. For details
4.4
Trap instruction exception handling starts when a TRAPA instruction is executed. If the UE bit is
set to 1 in the system control register (SYSCR), the exception handling sequence sets the I bit to 1
in CCR. If the UE bit is 0, the I and UI bits are both set to 1 in CCR. The TRAPA instruction
fetches a start address from a vector table entry corresponding to a vector number from 0 to 3,
which is specified in the instruction code.
