Breakpoint timing
Figure 7-15 shows the ARM7TDMI processor synchronous interrupt timing. The
timing parameter used in Figure 7-12 is listed in Table 7-12.
In Figure 7-15, BREAKPT changing in the LOW phase of MCLK (to signal a
watchpointed store) affects nCPI, nEXEC, nMREQ, and SEQ in the same phase.
