WebMay 10, 2024 · The bus has strong pullups. We occasionally have seen the I2C master get stuck in a state where the busy bit becomes set and remains set. We have not yet captured the event happening, but afterward it remains in the stuck state until we power cycle. When it's sitting in the stuck state, we observe that the SCL and SDA lines are high.

The data ("bits") are transferred as a sequence. Usually it is some application software that determines what data needs to be send, what address must be used and what data must be send to it.
