Figure 20: Terminating a READ Burst
PDF: 09005aef8404b23d
y68m_mobile_lpsdr.pdf – Rev. D 1/11 EN
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 20 (page 48) for each possible CAS la-
tency; data element n + 3 is the last desired data element of a longer burst.
