Abstract
Systems and methods related to serial communication devices are provided. An example integrated circuit (IC) device includes interface circuitry coupled to a two-wire serial communication bus having a serial clock (SCL) line and a serial data (SDA) bus line. The IC device further includes bus stuck recovery circuitry to monitor for a local SDA fault condition at the IC device based on a number of clock cycles during which an internal SDA signal (e.g., generated by the IC device) drives the SDA bus line to a first signal state, the clock cycles based on a clock signal received from the SCL line; and responsive to the local SDA fault condition, release the SDA bus line independent of the internal SDA signal, where the SDA bus line is in a second signal state different from the first signal state based on the release.
