ARM DDI 0180A
Interlocked MCR
If the data for an MCR operation is not available inside the ARM9TDMI pipeline
during its first decode cycle, the ARM9TDMI pipeline will interlock 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 will enter the decode stage of the coprocessor pipeline, and remain
there for a number of cycles before entering the execute stage. Figure 4-4 on page 4-12
gives an example of an interlocked MCR.
