15.4.1. Data Validity
The data on the SDA line must be stable during the HIGH period of the clock. The HIGH or LOW state of the data line can only change
when the clock signal on the SCL line is LOW (See Figure 25).

15.4.2. START and STOP Conditions
2
Within the procedure of the I
C-bus, unique situations arise, which are defined as START (S) and STOP (P) conditions (See Figure 26).
A HIGH to LOW transition on the SDA line while SCK is HIGH is one such unique case. This situation indicates a START condition.
LOW to HIGH transition on the SDA line while SCK is HIGH defines a STOP condition.
START and STOP conditions are always generated by the master. The bus is considered to be busy after the START condition. The
bus is considered to be free again a certain time after the STOP condition. The bus free situation is specified as t
in Table 6.
BUF
The bus stays busy if a repeated START (Sr) is generated instead of a STOP condition. In this respect, the START (S) and repeated
START (Sr) conditions are functionally identical (See Figure 27). The symbol S will be used to represent START and repeated START,
unless otherwise noted.
