Note:
Continuous-page READ bursts can be truncated with a BURST TERMINATE command
and fixed-length READ bursts can be truncated with a BURST TERMINATE command,
provided that auto precharge was not activated. The BURST TERMINATE command
should be issued x cycles before the clock edge at which the last desired data element is
valid, where x = CL - 1. This is shown in Figure 22 (page 52) for each possible CAS
latency; data element n + 3 is the last desired data element of a longer burst.
