Abstract:
A bus connection circuit connects a bus master and a plurality of bus slaves. The bus connection circuit includes a mirror area access detecting circuit and a processing circuit. The mirror area access detecting circuit detects that the bus master accesses a mirror area of a first bus slave of the plurality of bus slaves, and output a detection signal based on a detection result. The processing circuit executes processing preset in correspondence to the detection result, to an area or data as an access object, based on the detection result.
