WRITE Burst Termination
Data from any WRITE burst may be truncated using the BURST TERMINATE command (see Page 30), provided
that Auto Precharge was not activated. The input data provided coincident with the BURST TERMINATE
command will be ignored. This is shown in Figure 30. The BURST TERMINATE command may be used to
terminate a full-page WRITE which does not self-terminate.
