Multi-function interface

摘要

A multi-function interface includes a digital interface module and a configurable output impedance module. The digital interface module is operably coupled to pass a first type of input signal when the multi-function interface is in a first mode and operably coupled to pass a second type of input signal when the multi-function interface is in a second mode. The configurable output impedance module is operably coupled to the digital interface to provide a first output impedance when the multi-function interface is in the first mode and to provide a second output impedance when the multi-function interface is in the second mode.
