Figure 6-4  Transfer type examples

•

The first transfer is the start of a burst and is therefore nonsequential.

•

The master performs the second transfer of the burst immediately.

•

The master performs the third transfer of the burst immediately, but this time the 

slave is unable to complete and uses HREADY to insert a single wait state. 

•

The final transfer of the burst completes with zero wait states.
