Data for any WRITE burst may be concatenated with or truncated with a subsequent WRITE command. In either case, a
continuous flow of input data can be maintained. A WRITE command can be issued on any positive edge of clock following the
previous WRITE command. The first data element from the new burst is applied after either the last element of a completed
burst (Figure 27) or the last desired data element of a longer burst which is being truncated (Figure 28). The new WRITE
command should be issued x cycles after the first WRITE command, where x equals the number of desired data elements.
