During the first cycle, the ARM9E-S extracts the branch destination and the new
core state while performing a prefetch from the current PC. This prefetch is
performed in all cases, because by the time the decision to take the branch has
been reached, it is already too late to prevent the prefetch. In the case of

interlock in the case of
cycle.
During the second cycle, the ARM9E-S performs a fetch from the branch
destination, using the new instruction width, dependent on the state that has been
selected. If the link bit is set, the return address to be stored in r14 is calculated.
During the third cycle, the ARM9E-S performs a fetch from the destination +2 or
+4 dependent on the new specified state, refilling the instruction pipeline.
