A data transmission system includes a first bus; a first bus master coupled to the first bus; a second bus master coupled to the first bus; a bus arbiter coupled to the first and second bus masters to provide an authorization of bus master operation to the first and second bus masters selectively; and a bus request holding circuit, which is coupled between the second bus master and the bus arbiter. The bus request holding circuit holds a bus request signal supplied from the second bus master for an appropriate period of time in response to a signal from the first bus master.
