5.1.1
The chip controls interrupts by means of an interrupt controller. The interrupt controller has the
following features. The available interrupt sources are external interrupts (NMI, IRQ7 to IRQ0)
and internal interrupts (43 sources).
• Two interrupt control modes
• Priorities settable with IPRs
• Independent vector addresses
• Nine external interrupt pins
• DTC control
⎯ Either of two interrupt control modes can be set by means of the INTM1 and INTM0 bits
⎯ Interrupt priority registers (IPRs) are provided for setting interrupt priorities. Eight priority
⎯ NMI is assigned the highest priority level of 8, and can be accepted at all times
⎯ All interrupt sources are assigned independent vector addresses, making it unnecessary for
⎯ NMI is the highest-priority interrupt, and is accepted at all times. Rising edge or falling
⎯ Falling edge, rising edge, or both edge detection, or level sensing, can be selected for IRQ7
⎯ DTC activation is controlled by means of interrupts
in the system control register (SYSCR)
levels can be set for each module for all interrupts except NMI
the source to be identified in the interrupt handling routine
edge can be selected for NMI
to IRQ0
