For example, in the above embodiment, the upper limit value set in the bus hold time upper limit value setting unit 19 and the upper limit value set in the bus hold release time upper limit value setting unit 20 are fixed values. However, the MPU 4 may change the time at an arbitrary time.

Further, in FIGS. 3 and 4, the bus hold time timing and the interrupt input signal timing are separately described for the sake of simplicity, but it goes without saying that these can be expressed as one timing chart. Yes. For example, it is possible to indicate that an interrupt input signal is detected and the bus hold state is released while the bus hold time is being measured. It is also possible to design so that the bus hold state is not released even when the interrupt input signal 23 is detected.

As described above, by measuring the bus hold time, the bus hold state is prevented from occurring until the time exceeding the upper limit value, and by measuring the bus hold release time, the time exceeding the upper limit value in the receiving section is measured. Until the bus hold release state is generated, and when the interrupt input signal to the MPU4 becomes active, the bus hold state is released and the MPU in the receiving section is released.
When the interrupt input signal to M becomes inactive, M
Since it is also possible to put the PU in the bus hold state again, it is possible to balance the reduction of the influence of noise and the information processing that emphasizes performance or real-time property.
