ABSTRACT:
To provide a microcontroller having a function for stopping supply of a clock signal to a slave block and a function for properly stopping the access to a slave block to which supply of a clock signal is stopped. A microcontroller of the present invention has a master block101for controlling the whole microcontroller, slave blocks102and103to be controlled by the master block101,clock-signal control means106and107for controlling supply/stop of a clock signal in response to a clock control signal output from the master block101, and a default slave block104for outputting a response signal RESP instead of a slave block to which supply of a clock signal is stopped.
