Abstract
Briefly, in accordance with one embodiment of the invention an integrated circuit includes: a digital feedback control circuit to adjust the impedance of an interface circuit output buffer based, at least in part, on having adjusted the impedance of a non-data signal output buffer coupled to an external impedance. Briefly, in accordance with another embodiment of the invention, a method of digitally adjusting the impedance of an interface circuit output buffer comprises: digitally adjusting the impedance of a non-data signal output buffer coupled to an external impedance, and digitally adjusting the impedance of the interface circuit output buffer based, at least in part, on the digitally adjusted impedance of the non-data signal output buffer.
