In hardware-timed non-buffered sample mode, samples are acquired or generated continuously using hardware timing and no buffer. You enable this mode by using sample clock or change detection timing types and specifying a buffer size of 0. This mode is similar to hardware-timed single point sample mode but with slower performance and no error checking. Because there is no buffer if you use hardware-timed non-buffered sample mode, you should ensure that reads or writes execute fast enough to keep up with hardware timing.
