Abstract
Unique addresses for a plurality of devices may be programmed through a single external connection (pin) on each device by using a one of a plurality of different analog voltage or current values on the single external pin in combination with a serial clock of a serial data bus for each device requiring a unique binary address. The unique binary address is stored in the device after detection of certain number of clocks on the serial data bus. Once the unique binary address has been stored in the device, the single external connection may be used for another purpose such as a multifunction external connection. This unique binary address may be retained by the device until a power-on-reset (POR) or general reset condition occurs. Address detection and address load commands on the serial bus may also perform the same address definition and storage functions.
