When the contents of a MAC register are stored in a general-purpose register using an STS
instruction, an MA stage for accessing the multiplier is added to the STS instruction, as
described later. When the MA of the STS instruction contends with the operating multiplier
(mm), the MA is extended until the mm ends (the M—A shown in the dotted line box in figure
7.50) to create a single slot. The MA of the STS contends with the IF. Figure 7.50 illustrates
how this occurs, assuming MA and IF contention.
