Abstract
An access destination determining section determines whether an access is directed to regionor region. A regiondrive capability register and a regiondrive capability register set drive capabilities of output buffers when accesses to regionand regiongenerate, respectively. For example, if '1' is set to regiondrive capability register, when an access to regiongenerates, a Bufoutput enable signal is output at high level to enable outputs of Bufs. Therefore, a drive capability of a bus can be altered according to a region to which an access is made by a CPU or the like, thereby enabling prevention of unnecessary power consumption and generation of noise.
