operate in an input mode to receive signals from the trace;
a controller connected to the buffer, the controller being configured to:
control the buffer to output a synchronization pulse to the trace periodically at a time interval;
in response to each output of the synchronization pulse, switch the buffer from the output mode to the input mode;
in response to the switch of the buffer from the output mode to the input mode, listen for incoming data on the trace; and
