    • To provide an interrupt control device for avoiding an unwanted transition to a low power mode without a decrease in software quality. The interrupt control device receives an interrupt, and also receives a switching instruction to switch a target device from a normal power mode to the low power mode, the switching instruction being included in a transition program showing a transition procedure from the normal to low power mode. The interrupt control device manages an interrupt state, by switching between a disable state of disabling any interrupt, a first enable state of enabling an interrupt in a period of the transition procedure, and a second enable state of enabling an interrupt in a period other than the period of the transition procedure. If the interrupt is received in the first enable state, the interrupt control device abandons the switching instruction when subsequently receiving the switching instruction.
    • 提供一种中断控制装置,用于避免不必要的过渡到低功率模式而不降低软件质量。 中断控制装置接收中断,并且接收将目标装置从正常功率模式切换到低功率模式的切换指令,切换指令包括在转换程序中,该转换程序示出从正常到低功率模式的转换过程 。 中断控制装置通过切换禁止任何中断的禁止状态,在转换过程的时段中使能中断的第一使能状态和允许中断之后的中断的第二使能状态来管理中断状态 过渡程序的时期。 如果在第一使能状态下接收到中断,则当随后接收到切换指令时,中断控制装置放弃切换指令。
