The processor 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.
read back-to-back with a write.
Basic read and write cycles are used to show a back-to-back cycle, but there is no restriction as to the type
of operations to be placed back to back. The initiation of a back-to-back cycle is not user definable.
