Data valid
The data on SDA is stable during the high period of SCL. The state of SDA is changed
during the low phase of SCL. The only exceptions to this are the start (S) and stop (P)
conditions as defined below. (See
Figure 22. SDA data valid
Start (S) and Stop (P) conditions
A START (S) condition defines the start of a V2W message. It consists of a high to low
transition on SDA while SCL is high.
A STOP (P) condition defines the end of a V2W message. It consists of a low to high
transition on SDA while SCL is high.
After STOP condition the bus is considered free for use by other devices. If a repeated
START (Sr) is used instead of a stop then the bus stays busy. A START (S) and a repeated
START (Sr) are considered to be functionally equivalent.
