CHAPTER 3 INTERRUPT
3.11 Delay Interrupt Generation Module
The delay interrupt generation module is a module that generates an interrupt for task
switching. Using this module allows generation and clearing of an interrupt request to
the F

MC-16LX CPU by software.

List of registers in delay interrupt generation module
The delay interrupt generation module, delay interrupt factor originate/clear register (DIRR:
delayed interrupt request register), has the register configuration shown below.
The delay interrupt factor originate/clear register (DIRR) is a register used to generate/clear the
delay interrupt factor. Writing "1" to the register results in a request to delay an interrupt, and
writing "0" clears the delay interrupt request. Resetting causes the factor clear state. Either "0"
or "1" can be written to the reserve bit area. For future expansion, however, Fujitsu
recommends using the set bit or clear bit instructions to access this register.
