Claim Text:
1. An integrated circuit comprising: first circuitry configured to sense a change in an input voltage; second circuitry configured, in response to said first circuitry sensing a first change in said input voltage, to change a logic state of a first logic signal from a first logic state to a second logic state while said first change is occurring and then change from the second logic state back to the first logic state when said first change ends and, in response to said first circuitry sensing a second change in said input voltage, to change a logic state of a second logic signal from a third logic state to a fourth logic state while said second change is occurring and then change from the fourth logic state back to the third logic state when said second change ends; and third circuitry configured, in response to the change in said first logic signal or change in said second logic signal, to produce a third signal indicative of said first circuitry sensing said change in said input voltage.
