Data Transfer
4.3
START and STOP Conditions
The host initiates and terminates a data transmission. The transmission is initiated when the
host issues a START condition on the bus, and is terminated when the host issues a STOP
condition. Between START and STOP conditions, the bus is considered busy. As shown below,
START and STOP conditions are signaled by changing the level of the SDA line when the SCL
line is high.
Figure 4-4.
START and STOP Conditions

Address Packet Format
All address packets are 9 bits long, consisting of 7 address bits, one READ/WRITE control bit
and an acknowledge bit. If the READ/WRITE bit is set, a read operation is performed, otherwise
a write operation is performed. When the device recognizes that it is being addressed, it will
acknowledge by pulling SDA low in the ninth SCL (ACK) cycle. An address packet consisting of
a slave address and a READ or a WRITE bit is called SLA+R or SLA+W, respectively.
The most significant bit of the address byte is transmitted first. The address sent by the host
must be consistent with that selected with the option jumpers.
