WebJul 20, 2024 · The worst-case comm. errors are lockup conditions such as when a clock pulse was missed and the sender keeps the data bit active. The receiver could reset, but the sender doesn't know. There are many scenarios of lock-up, so the system design must ensure there is a recovery mechanism. WebMar 17, 2024 · The two lines of the I2C-bus, SDA and SCL, are bi-directional and open-drain, pulled up by resistors. SCL is a Serial Clock line, and SDA is a Serial Data line. Devices on the bus pull a line to ground to send a logical zero and release a line (leave it floating) to send a logical one.
