Note:
Fixed-length WRITE bursts can be truncated with the BURST TERMINATE command.
When truncating a WRITE burst, the input data applied coincident with the BURST TER-
MINATE command is ignored. The last data written (provided that DQM is LOW at that
time) will be the input data applied one clock previous to the BURST TERMINATE com-
mand. This is shown in Figure 35 (page 65), where data n is the last desired data
element of a longer burst.
