COMMAND
Data for any WRITE burst may be truncated with a subsequent READ command, and
data for a fixed-length WRITE burst may be immediately followed by a READ command.
After the READ command is registered, the data inputs will be ignored, and WRITEs will
not be executed. An example is shown in Figure 21 on page 30. Data n + 1 is either the
last of a burst of two or the last desired of a longer burst.
