Read Interrupted by Precharge Command and Burst Read Stop Cycle @Burst Length = 8
Notes: 1. The Burst Stop command is valid at every page burst length. The data bus goes to high-Z after the CAS latency from the
Burst Stop command is issued.
2. The interval between Read command (column address presented) and Burst Stop command is 1 cycle (min).
