  • Patent number: 8219731
    Abstract: Provided are a data processor, and a control system, in which an interrupt controller and an event link controller are adopted. The event link controller responds to a generated event signal to output a start control signal for controlling start of an operation of a circuit module. The circuit module is able to generate an event signal. The event link controller generates the start control signal according to the correspondences between event signals and start control signals which are defined by event control information. The links between the event signals and start control signals can be prescribed by the event control information. Therefore, operations of circuit modules prescribed by such links can be controlled sequentially. The control neither involves save and return processes by CPU as in the interrupt processing, nor needs priority level control as executed on competing interrupt requests.

  • Patent number: 6820179
    Abstract: A semiconductor device which has an internal circuit for performing a circuit operation corresponding to a signal inputted or outputted through an input/output interface circuit adapted to a serial bus. The semiconductor device has a non-volatile storage circuit for storing identification data. Internal identification data stored in the non-volatile storage circuit is compared with external identification data included in an input signal supplied through the serial bus by a comparator circuit. A control circuit is responsive to a match detecting signal generated by the comparator circuit to perform a circuit operation corresponding to an input signal subsequently supplied through the serial bus to change the internal identification data stored in the non-volatile storage circuit.

  • Patent number: 5524087
    Abstract: A variable wave forming circuit is provided which produces signals of various waveforms (e.g., sine, triangular or trapezoidal waves) and various frequencies. A random access memory (memory means) 121 to store wave formation information on waveform is provided. According to the wave formation information stored in the memory means, the updating or keeping of a digital value in an increment/decrement circuit 123 is controlled and the digital value is digital/analog-converted by a digital/analog (D/A) conversion circuit 124, which is controlled by a digital value control means that includes the increment/decrement circuit 123. By writing appropriate wave formation information into the memory means, it is possible to produce signals of desired waveforms.
