This parameter is characterized and not 100% tested. 2.AC measurement conditions: RL (connects to Vcc): 1.3K Ω Input pulse voltages: 0.3 Vcc to 0.7 Vcc Input rise and fall times: ≦50 ns Input and output timing reference voltages: 0.5Vcc Device Operation Clock and Data Transitions: The SDA pin is normally pulled high with an external device. Data on the SDA pin may change only during SCL low time periods (refer to Figure 4). Data changes during SCL high periods will indicate a start or stop condition as defined below. Start Condition: A high-to-low transition of SDA with SCL high is a start condition which must precede any other command (refer to Figure 5). |
