Abstract
A data communication apparatus comprises a line driver configured to couple the data communication apparatus to a 1-wire serial bus; and a controller configured to: transmit a plurality of synchronization pulses over the 1-wire serial bus after a sequence start condition (SSC) has been transmitted over the 1-wire serial bus, the plurality of synchronization pulses being configured to synchronize one or more receiving devices coupled to the 1-wire serial bus to an untransmitted transmit clock signal; initiate an interrupt handling procedure when the plurality of synchronization pulses is encoded with a first value; and initiate a read transaction or a write transaction with at least one of the one or more receiving devices coupled to the 1-wire serial bus when the plurality of synchronization pulses is encoded with a second value.
