I2C bus specifications - CERN
espace.cern.chThe I2C Bus Topology for the PS and 2S is shown in Figure 1. The optical link communication ASIC; namely the lpGBT (low power GigaBit Transceiver) is equipped with two independent I2C master interfaces that realize two independent I2C busses. The lpGBT I2C master interface is the only master interface permitted to connect on the bus.

AN-686 APPLICATION NOTE - Analog Devices
www.analog.comI2C state machine will determine the effectiveness of the clocking approach.) The method is quite simple. It is the master’s job to recover the bus and restore control to the main program. When the master detects the SDA line stuck in the low state, it merely needs to send some additional clocks and gener-ate a STOP condition.

ww1.microchip.comDec 08, 2006 · master that an input state has changed. The interrupt capture register captures port value at this time. The Power-on Reset sets the registers to their default val-ues and initializes the device state machine. Three device inputs (A0 - A2) determine the I2C address and allow up to eight I/O expander devices to share the same I2C bus. 1.1 Pin ...
Automotive Audio Bus A2B Transceiver …
www.analog.commaster A2B transceiver is programmable over a control port (I2C) for configuration and read back. An extension of the con-trol port protocol is embedded in the A2B data stream, which grants direct access of registers and status information on slave transceivers as well as I 2C to I C communication over distance.
