[ Read Interrupted by Burst Terminate ]

Similar to a precharge, the burst terminate command, TBST, can interrupt the burst read operation

and disable the data output. The READ to TBST interval is a minimum of one CLK. TBST is mainly

used to interrupt FP bursts. The figures below show examples, of how the output data is terminated

with TBST.
