Section 5 Interrupt Controller

Features

Two interrupt control modes

Two interrupt control modes can be set by means of the INTM1 and INTM0 bits in the system

control register (SYSCR).

Priorities settable with ICR

An interrupt control register (ICR) is provided for setting in each module interrupt priority

levels for all interrupt requests excluding NMI and address breaks.

Three-level interrupt mask control

By means of the interrupt control mode, I and UI bits in CCR and ICR, 3-level interrupt mask

control is performed.

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.

Forty-one external interrupt pins

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 independently selected for

IRQ15 to IRQ0. When the EIVS bit in the system

control register 3 (SYSCR3) is cleared to 0, the IRQ6 interrupt is generated by

IRQ6 or KIN7

KIN0. The IRQ7 interrupt is generated by IRQ7 or KIN15 to KIN8. When the EIVS bit in

the system control register 3 (SYSCR3) is set to 1, interrupts are requested on the falling edge

KIN15 to KIN0. For WUE15 to WUE8, either rising-edge or falling-edge detection can be

selected individually for each pin regardless of the EIVS bit setting.

Two interrupt vector addresses are selectable

H8S/2140B Group compatible interrupt vector addresses or extended interrupt vector

addresses are selected depending on the EIVS bit in system control register 3 (SYSCR3). In

extended mode, independent vector addresses are assigned for the interrupt vector addresses of

KIN7 to KIN0 or KIN15 to KIN8 interrupts.

General ports for IRQ15 to IRQ0 input are selectable
