Semiconductor data processing device, time-triggered communication system, and communication system

摘要: The variation of the timing starting interrupt processing in response to a timer request is reduced regardless condition other interrupts. A semiconductor data device incorporated each plural electronic control devices coupled network for time-triggered communication system provided with central unit, circuit and an circuit. has local time use issues, based on counting by timer, communication. When received, performs cause unit delay, predetermined reservation time, be performed request.
