Delay Interrupt Generation Module Outline
The delay interrupt generation module is a module that generates interrupts for switching tasks. Generation of
a hardware interrupt request is performed by software.
Delay interrupt generation module outline
Using the delay interrupt generation module, hardware interrupt request is generated and released by software.

Interrupt request latch
A latch that retains settings on delay interrupt request generation/release register (generation or release of delay
interrupt request).
Delay interrupt request generation/release register (DIRR)
Generates or releases delay interrupt request.
Interrupt number
An interrupt number used in delay interrupt generation module is as follows:
Interrupt number: #42 (2A
H
)
Function and control
Cause of interrupt
Set “1” in R0 bit of delay interrupt request generation/release register (DIRR: R0=1),
generating an interrupt request.
Set “0” in R0 bit of delay interrupt request generation/release register (DIRR: R0=0),
releasing an interrupt request.

Interrupt control
No setting of permission register is provided.
Interrupt flag
Retained in DIRR: R0 bit
