  • Patent number: 7802030
    Abstract: The present invention provides an interrupt generation circuit that can reduce the time between the moment a monitored object actually enters a desired state and the moment an interrupt is generated. An external event detection unit 101 detects the effective edge of an external event signal. A count period generation circuit 103 generates external event division signals which are counted by the main timer 104 and each of which has a period that is 1/N of the time interval between the effective edges of the immediately preceding external event signal. A compare register 105 stores a value corresponding to the time at which an interrupt is to be generated. When the count value of the main timer 104 becomes equal to or larger than the value stored in the compare register 105, the interrupt determination circuit 106 generated an interrupt.

  • Patent number: 7795921
    Abstract: A semiconductor integrated circuit includes a sampling unit, a delay unit, a first operating unit and a second operating unit. The sampling unit samples an input signal supplied from an external circuit in synchronization with a clock signal, and outputs the sampled input signal as a first signal. The delay unit delays the first signal in synchronization with the clock signal, and outputs the delayed first signal as a second signal. The first operating unit operates whether a signal level of the input signal is sustained equal to or longer than a predetermined period based on the first and second signals, and outputs an output signal in synchronization with the clock signal when the signal level of the input signal is sustained equal to or longer than the predetermined period. A signal level of the output signal is sustained equal to or longer than the predetermined period. The second operating unit asynchronously controls the sampling unit based on the input signal and the output signal.
