To efficiently personalize multiple bus interfaces, an input/output (I/O) integrated circuit (IC) is provided. This I/O IC can include two local bus control blocks, wherein each local bus control block can be configured to provide a selected personality. The selected personality can include an IDE (intelligent drive electronics) interface, an MPEG-TS (Moving Picture Experts Group Transport Stream) interface, a GPIO (general purpose input/output) interface, or a PCI (peripheral component interconnect) interface. Advantageously, when the two local bus control blocks are configured, they can provide one of a combined IDE/MPEG-TS interface, a combined IDE/GPIO interface, and the PCI interface. Thus, the I/O IC has a common set of pins that can be allocated to one or more bus types, depending on net pin count.
