Abstract: A receiving circuit has a clock generator circuit, a synchronization circuit and a controller. The clock generator circuit is configured to generate a base clock signal with a base frequency. The synchronization circuit is configured to synchronize edges in the base clock signal with edges in a Manchester-encoded data signal received over a serial bus. The controller is configured to detect that a first pulse received from the serial bus has a duration corresponding to a pulse duration defined for a first type of sequence start condition that indicates a first type of transaction during which the Manchester-encoded data signal is received over the serial bus; configure a first timer to expire after a first timeout period; and ignore the first pulse when signaling consistent with the first type of sequence start condition has not been received before the first timer expires.
