10.4 Byte transfer
10.5 Data transfer
10.6 Start and stop conditions
10.7 Acknowledgment
Each byte (8 bits) is transferred with the MSB first (see
Table 16:
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.
Both data and clock line will 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 a start condition (S); see
Figure
a stop condition (P).
The number of data bits transferred between the start and stop conditions from the
transmitter to receiver is not limited. Each byte of eight bits is followed by one
acknowledge bit (see
master and the master generates an extra acknowledge related clock pulse.
