One embodiment of the present invention provides a system that keeps track of transitions on signal lines in order to latch a dataword in a stream of datawords. This stream of datawords is generated so that each transition between successive datawords involves a minimum number of transitions on a set of signal lines. During operation, the system monitors the set of signal lines that carries the stream of datawords. Upon detecting a predetermined number of transitions on the set of signal lines, the system waits a fixed time interval to ensure that a dataword is ready to be latched, and then latches the dataword.
