Figure 5.4 shows the simplest transfer with no wait states. The master
drives the address and control signals onto the bus after the rising edge
of CLK. The slave then samples the address and control information on
the next rising edge of the clock. After the slave has sampled the
address/control, it can start to drive the appropriate response. The bus
master samples the response on the third rising edge of the clock.
Figure 5.4
Simple Transfer
This example shows how the address and data phases of the transfer
occur during different clock periods. In fact, the address phase of any
transfer occurs during the data phase of the previous transfer. This
overlapping of address and data is fundamental to the pipelined nature
of the bus. It allows for high-performance operation while still providing
adequate time for a slave to provide the response to a transfer.
Figure 5.5 shows a transfer with wait states. A slave can insert wait
states into any transfer, allowing additional time for completion. For write
operations, the bus master holds the data stable throughout the extended
cycles. For read operations, the slave does not have to provide valid data
until the transfer is about to complete.
