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

behavior of the address lines for both internal and external termination. Note that when external
termination is used, the address lines change with SIZ[1:0].
