Note 1: Devices participating in a transfer time out when any clock low exceeds the 25ms minimum timeout period. Devices that
have detected a timeout condition must reset the communication no later than the 35ms maximum timeout period. Both a
master and a slave must adhere to the maximum value specified as it incorporates the cumulative stretch limit for both a
master (10ms) and a slave (25ms).
Note 2: Specifications to -40 ° C are guaranteed by design, not production tested.
