Circuits and methods for reducing pin count in multiple-mode integrated circuit devices

A method of controlling a terminal of an integrated circuit includes determining a frequency ratio between a frequency of a signal and a frequency of another signal received by an integrated circuit. A selected signal appearing at a selected terminal of the integrated circuit is selectively interpre...

Zusammenfassung:	A method of controlling a terminal of an integrated circuit includes determining a frequency ratio between a frequency of a signal and a frequency of another signal received by an integrated circuit. A selected signal appearing at a selected terminal of the integrated circuit is selectively interpreted in accordance with an operating mode when the frequency ratio is below a selected value and in accordance with another operating mode when the frequency of the signal is above a selected value.
