Data Transfer Operation
18.4.7.3 Line Write Bus Cycles
Figure 18-16 shows a line access write with zero wait states. It begins like a basic write bus
cycle 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 Figure 18-12, AS and CSx remain
asserted throughout the burst transfer. This example shows the behavior of the address lines
for both internal and external termination. Note that with external termination, address
lines, like SIZ, TT, and TM, hold the same value for the entire transfer.
