To facilitate such recording, the FIFO is designed to overwrite the oldest sample upon overflow. This allows the FIFO, when full, to continue to accept new data and to automatically retain only the newest data up to its maximum capacity.
To facilitate such recording, the FIFO is designed to overwrite the oldest sample upon overflow. This allows the FIFO, when full, to continue to accept new data and to automatically retain only the newest data up to its maximum capacity.


In operation, recording is started and the FIFO begins filling with incoming samples. If allowed to record long enough, the FIFO will become full and, upon each new incoming sample, the oldest recorded sample will be discarded to make space for rhe new sample. When the trigger arrives, recording stops and the recorded samples may be read from the FIFO. Overflows are ignored because any lost (overwritten) data that predates the recorded data is irrelevant.
