SEMICONDUCTOR DEVICE AND CONTROL METHOD THEREOF

摘要

According to one aspect, a module 11_1 includes a communication circuit 111 that performs data communication with an externally-provided control device 12 through a communication bus 13, and an interrupt signal generation circuit 113 that, when an interrupt instruction signal I1 output from the communication circuit 111 becomes an active state, generates an interrupt signal and outputs the generated interrupt signal to the communication bus 13, the interrupt signal being defined by using a bus potential undefined in a data communication standard.

1. A semiconductor device comprising:
a communication circuit that performs data communication with an externally-provided control device through a bus; and a first interrupt signal generation circuit that, upon receiving an interrupt instruction from the communication circuit, generates an interrupt signal and outputs the generated interrupt signal to the bus, the interrupt signal being defined by using a bus potential undefined in a data communication standard.
