Apparatus for disabling unused cache tag input/output pins during processor reset by sensing pull-down resistors connected to disabled pins

摘要

A method of programming a cache tag comparator by designing a semiconductor device's internal circuitry such that an input/output pin of the device may be programmed by an external resistor to ground that will indicate during the reset phase of the device that an alternate function for the pin is to be selected or that the pin itself is to be disabled.
