Abstract
A system in accordance with the invention provides a chipset for use generally in a PC-type system and that includes a plurality of programmable I/O (PIO) pins. Each of the PIO pins can be programmed to carry signals in accordance with any function in a function pool. In one embodiment, the number of PIO pins total 32 and the number of functions total 70. Such programmability allows a single-chip chipset to be vendor platform-generic while simultaneously minimizing pin count.
