The ARM7TDMI processor controls these instructions in the same way as for memory
to coprocessor transfers, with the exception that the nRW line is inverted during the
transfer cycle.
The cycle timings are listed in Table 6-18 where:
•
•
b represents the busy cycles
n represents the number of registers.
