Abstract: A method for placing a device in a selected 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 user-controlled 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. The selected operating mode may be a reduced power consumption mode, for example, or another operating mode of the device, such as a daisy-chain mode of operation, or a mode that accommodates programming of analog input range.
