ABSTRACT:
Described herein are methods and systems for conducting computer system communications with a number of different devices that communicate with the computer system in a number of different protocols via a protocol-shared combination host controller. Combination host controller has a reduced set of pins for handling communication in a plurality of communication protocols. The total number of pins needed for driving communication in a plurality of communication protocols is reduced by sharing at least one control pin or at least one data pin or combination thereof between at least some of the plurality of communication protocols. In one embodiment, data communications in different protocols overlapping in time can be interleaved onto to a shared data path by suspending a current transmission until a later higher priority transmission is complete.
