Abstract
An external bus controller which is configured such that, when an external device having a data width smaller than that of an external bus is connected to the external bus, the signal lines of the external bus can be freely selected. This external bus controller includes a first exchange, which converts the data width of input/output data so as to compensate for differences between the data width of the internal bus and the data width of an external device, and a second exchange, which exchanges signal lines between the first exchange and the used signal lines. The signal lines to be used are set for each external device using configuration pins or similar means.
