摘要: A method for placing a device in selected mode of operation. The comprises the steps initializing select signal (307) into first logic state, asserting second and returning to state within user-controlled time window. is also described that includes means detecting transitions at input clock (306), changing operating response predetermined number input, occurring between input. may be reduced power consumption mode, example, or another device, such as daisy-chain operation, accommodates programming analog range.
