PRODUCTION DATA.
Figure 39 shows the handshaking between the master (host) and the slave (CDCUN1208LP) that the I2C protocol supports. In all cases, the master drives the SCL (clock line); however, depending on the direction of transfer/acknowledgment, the master or the slave device drives SDA (data line).
