Section 5 Interrupt Controller
5.1
Features
•
Two interrupt control modes
Any of two interrupt control modes can be set by means of the INTM1 and INTM0 bits in the
interrupt control register (INTCR).
•
Priorities settable with IPR
An interrupt priority register (IPR) is provided for setting interrupt priorities. Eight priority
levels can be set for each module for all interrupts except NMI. NMI is assigned the highest
priority level of 8, and can be accepted at all times.
•
Independent vector addresses
All interrupt sources are assigned independent vector addresses, making it unnecessary for the
source to be identified in the interrupt handling routine.
•
Seventeen external interrupts
NMI is the highest-priority interrupt, and is accepted at all times. Rising edge or falling edge
can be selected for NMI. Falling edge, rising edge, or both edge detection, or level sensing, can
be selected for

•
DTC and DMAC control
DTC and DMAC activations are performed by means of interrupts.
