Abstract
In a semiconductor device having an MPU and a plurality of peripheral devices controlled by the MPU through a bus, to facilitate the interconnection of the peripheral devices without the use of the MPU, improve response speed and the processing speed of a main program by eliminating an interrupt processing from the processings of the MPU, facilitate changes in the interconnection of the peripheral devices, and enable a reduction in the number of external terminals, event buses for transmitting event signals are provided between the peripheral devices or between the peripheral devices and the external terminals so that the connection between the peripheral devices and the external terminals can be switched by the multiplexers.
