Abstract
A method for placing a device in a reduced power-consumption mode of operation. The method comprises the steps of initializing a device select signal into a first logic state, asserting the device select signal in a second logic state, and returning the device select signal to the first logic state within a first predetermined time window. A device is also described that includes means for detecting logic state transitions at a device select input and a clock input, and means for changing operating mode of the device in response to a predetermined number of logic state transitions at the clock input, occurring between logic state transitions at the device select input.
