When the second MA of the MAC.W instruction contends with IF, the slot will split as usual.
Figure 7.35 illustrates a case of this type. This figure assumes MA and IF contention.
The second MA of a MAC.W instruction does not contend with an mm generated by a
preceding multiplication instruction (figure 7.36).
