Data Transfer Operation
Figure 18-10 shows a write cycle with fast termination.
18.4.6 Back-to-Back Bus Cycles
The MCF5307 runs back-to-back bus cycles whenever possible. For example, when a
longword read is started on a word-size bus, the processor performs two back-to-back word
read accesses. Back-to-back accesses are distinguished by the continuous assertion of TIP
throughout the cycle. Figure 18-11 shows a read back-to-back with a write.
