17.5.6 Back-to-Back Bus Cycles
The MCF5235 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.
