Abstract: A controller is provided that includes a serial data (SDA) line interface to connect the controller to an SDA line of a two-wire, shared, serial data bus. The controller includes processing circuitry to sample the SDA line to obtain samples of a voltage level on the SDA line, and monitor the samples. The processing circuitry detects a predetermined number of consecutive ones of the monitored samples at a low voltage level, without a low-to-high transition in the voltage level. The processing circuitry indicates a stuck SDA condition based on the detected, predetermined number of consecutive ones of the monitored samples.
