5.1.1
The H8S/2357 Group controls interrupts by means of an interrupt controller. The interrupt controller has the following
features:
Two interrupt control modes
Priorities settable with IPR
Independent vector addresses
Nine external interrupts
DTC and DMAC control
Any of two interrupt control modes can be set by means of the INTM1 and INTM0 bits in the system control
An interrupt priority register (IPR) is provided for setting interrupt priorities. Eight priority levels can be set for
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 the source to be
NMI is the highest-priority interrupt, and is accepted at all times. Rising edge or falling edge can be selected for
Falling edge, rising edge, or both edge detection, or level sensing, can be selected for IRQ7 to IRQ0.
DTC and DMAC activation is performed by means of interrupts.
