Fixed-length READ bursts may 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 17 on page 29 for each possible CL; data
element n + 3 is the last desired data element of a longer burst.
