6.5.1.2 I2C Bus Definitions

The device is I2C-compatible and the bus definitions are listed in Table 6-2.

Table 6-2 I2C Symbol Set
CONDITIONSYMBOLSOURCEDESCRIPTION
STARTSControllerBegins all bus transactions. A change in the state of the SDA line, from high to low, while the SCL line is high, defines a START condition. Each data transfer initiates with a START condition
STOPPControllerTerminates all transactions and resets bus. A change in the state of the SDA line from low to high while the SCL line is high defines a STOP condition. Each data transfer terminates with a repeated START or STOP condition.
IDLEIControllerBus idle. Both SDA and SCL lines remain high.
ACK (Acknowledge)AController/TargetHandshaking bit (low). Each receiving device, when addressed, is obliged to generate an acknowledge bit. A device that acknowledges must pull down the SDA line during the acknowledge clock pulse in such a way that the SDA line is stable low during the high period of the acknowledge clock pulse. Take setup and hold times into account.
NACK (Not Acknowledge)AController/TargetHandshaking bit (high). On a controller receive, data transfer termination can be signaled by the controller generating a not-acknowledge on the last byte that has been transmitted by the target.
READRControllerActive-high bit that follows immediately after the target address sequence. Indicates that the controller is initiating the target-to-controller data transfer. The number of data bytes transferred between a START and a STOP condition is not limited and is determined by the controller device. The receiver acknowledges data transfer.
WRITEWControllerActive-low bit that follows immediately after the target address sequence. Indicates that the controller is initiating the controller-to-target data transfer. The number of data bytes transferred between a START and a STOP condition is not limited and is determined by the controller device. The receiver acknowledges data transfer.
REPEATED STARTSrControllerGenerated by controller, same function as the START condition (highlights the fact that STOP condition is not strictly necessary.)
BLOCK ACCESSBControllerActive-high bit that indicates the controller is initiating a block access data transfer.
