Terminating a READ Burst
Note:
Continuous page bursts can be truncated with the BURST TERMINATE command, and
fixed-length READ bursts may be truncated with a BURST TERMINATE command, pro-
vided 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 for each possible CL; data element n + 3 is the
last desired data element of a longer burst.
