Embodiment Construction

[0019] see figure 1 , there is described a system designated 10 representing any system, but in particular an electronic system in which a plurality of devices communicate with each other via a common network, in particular a bus structure. It should be understood that in figure 1 The system is an electronic system, specifically an integrated circuit system with a controller IC and a plurality of subordinate ICs, the controller IC and the plurality of subordinate ICs communicate with each other through a system bus and a bus management system, the principle of the present invention Can be applied to other similar electronic and / or non-electronic systems.

[0020] figure 1 The system 10 described in is specifically an I 2 C bus / protocol system (I 2 C system). The I 2 C System 10 includes an I 2 The command issuing IC12 of the C bus communication is generally indicated as 18 . Command-issuing IC 12 may be known as a master IC, such as a CPU, operable on bus 18 to initiat...

Abstract

An apparatus, system and method provides for the modification or programmability of an address of an I<2>C device. The modification or programming may be accompmlished via an input signal received by an I / O terminal of the device. In another form, the present invention also provides for substantially simultaneous modification of first and second addresses of respective first and second I<2>C devices. The modification or programming may be accomplished via an input signal received by an I / O terminal coupled to both the first and second I<2>C devices. The present invention obviates bus contention problems in an I2C bus / protocol system due to IC address conflict through the ability to modify (change) or program the I<2>C address. Modification or programming can be accommplished during the design phase or thereafter via software.

Description

technical field [0001] The present invention relates to the use of I 2 C-bus / protocol integrated circuits, specifically related to the use of I 2 Same address bus issue in integrated circuit systems for C bus / protocol. Background technique [0002] Integrated circuits or ICs are widely used in all kinds of electronic devices today. ICs are generally designed to behave in a specific way to perform a specific function. As a result, modern electronic devices typically require many different ICs to function. The ICs of modern electronic devices must be able to cooperate with each other in order to communicate with each other (receive and / or send data / information) in an orderly manner. [0003] Cooperation and communication in an IC environment includes the ability of one IC to send data / information to and / or receive data / information from another IC in response to an inquiry signal from another IC. This is typically accomplished by providing communication links or channels b...
