• Two interrupt control modes
• Priority can be assigned by the interrupt priority register (IPR)
• Independent vector addresses
• Seventeen external interrupts
• DTC and DMAC control
• CPU priority control function
Any of two interrupt control modes can be set by means of bits INTM1 and INTM0 in the
interrupt control register (INTCR).
IPR provides for setting interrupt priory. Eight levels can be set for each module for all
interrupts except for the interrupt requests listed below. The following eight interrupt requests
are given priority of 8, therefore they are accepted at all times.
 NMI
 Illegal instruction
 Trace
 Trap instruction
 CPU address error
 DMA address error (occurred in the DTC and DMAC)
 Sleep instruction
 Break interrupt
All interrupt sources are assigned independent vector addresses, making it unnecessary for the
source to be identified in the interrupt handling routine.
NMI is the highest-priority interrupt, and is accepted at all times. Rising edge or falling edge
detection can be selected for NMI. Falling edge, rising edge, or both edge detection, or level
sensing, can be selected for IRQ15 to IRQ0.
DTC and DMAC can be activated by means of interrupts.
The priority levels can be assigned to the CPU, DTC, and DMAC. The priority level of the
CPU can be automatically assigned on an exception generation. Priority can be given to the
CPU interrupt exception handling over that of the DTC and DMAC transfer.
