Semiconductor integrated circuit and method for controlling semiconductor integrated circuit

A method for controlling a semiconductor integrated circuit including a first master circuit, a second master circuit, and a first slave circuit, the method comprising:

• determining, by a first slave circuit being assigned to the first master circuit, that an access request signal is sent from the first master circuit when an identification information is a first value,
• wherein a first bus is coupled to the first master circuit, the second master circuit, and the first slave circuit;
• transmitting, by a bus controller, the access request signal to the first slave circuit via the first bus;
• directing, by a system controller, the bus controller to substitute the first value for a second value on the identification information of the access request signal received from the second master circuit when the first master circuit is in the deactivated state;
• and
• writing, by the bus controller, the first value on the identification information of the access request signal received from the second master circuit, after receiving the indication from the system controller.
