Product data sheet
7.1 Bit transfer
7.2 Start and stop conditions
7.3 System configuration
One data bit is transferred during each clock pulse. The data on the SDA line must remain
stable during the HIGH period of the clock pulse as changes in the data line at this time
will be interpreted as a control signal (see
Both data and clock lines remain HIGH when the bus is not busy. A HIGH-to-LOW
transition of the data line while the clock is HIGH is defined as the START condition (S).
A LOW-to-HIGH transition of the data line while the clock is HIGH is defined as the STOP
condition (P), (see
A device generating a message is a ‘transmitter’, a device receiving a message is the
‘receiver’. The device that controls the message is the ‘master’ and the devices which are
controlled by the master are the ‘slaves’, (see
