WebJul 9, 2024 · Answer. The clock of the I2C bus is composed of four regions: Low time. Rise time. High time. Fall time. Because the I2C module uses pins in open-drain mode, the fall time is relatively negligible, since the drivers will be pulling low reasonably quickly. The other three times compose the overall clock speed. WebThe I 2C protocol is based on two signals: serial clock line (SCL) and serial data line (SDA).

But, if the last bit was 0, SDA remains low even after the timeout was exceeded. Thus, we might end up with the case, where the slave has finally released SCL after the timeout but SDA is still low. エクセル csv 0 消さない
