The I2C-bus specification1 PREFACE 1.1 Version 1.0 - 1992 This version of the 1992 I2C-bus specification includes the following modifications: ?Programming of a slave address by software has been omitted. The realization of this feature is rather complicated and has not been used. ?The “low-speed mode” has been omitted. This mode is, in fact, a subset of the total I2C-bus specification and need not be specified explicitly. ?The Fast-mode is added. This allows a fourfold increase of the bit rate up to 400 kbit/s. Fast-mode devices are downwards compatible i.e. they can be used in a 0 to 100 kbit/s I2C-bus system.
