If the data for an MCR operation is not available inside the ARM9EJ-S core pipeline
during its first Decode cycle, then the ARM9EJ-S core pipeline interlocks for one or
more cycles until the data is available. An example of this is where the register being
transferred is the destination from a preceding LDR instruction. In this situation the
MCR instruction enters the Decode stage of the coprocessor pipeline, and remains there
for a number of cycles before entering the Execute stage.
Figure 8-5 shows an example of an interlocked MCR.
