with data driven one clock after TS. The next pipelined burst data is driven a cycle after the write
data is registered (on the rising edge of S6). Each subsequent burst takes a single cycle. Note that
as with the line read example in
This example shows the behavior of the address lines for both internal and external termination.
Note that when external termination is used, the address lines change with TSIZ[1:0].
