Abstract
A comparison circuit compares a burst access request from a bus controller with an access mode that is supported by an external memory device and that is set in a device information setting register. When the burst access request does not match the access mode that is supported by the external memory device, a control signal generation circuit accesses the external memory device in an access mode different from that of the burst access request from the bus controller. At this time, the control signal generation circuit controls the external memory device so that the data is output to the bus controller in the order corresponding to the burst access request from the bus controller. This enables the bus controller to read the correct data according to the burst access request.
