Coprocessor timing
Figure 7-10 shows the ARM7TDMI processor coprocessor timing. The timing
parameters used in Figure 7-10 are listed in Table 7-10.
In Figure 7-10, usually nMREQ and SEQ become valid T
MCLK. In this cycle the core has been busy-waiting for a coprocessor to complete the
instruction. If CPA and CPB change during phase 1, the timing of nMREQ and SEQ
depends on T
2, and so the timing of nMREQ and SEQ is always T
