Status Flag Clearing Timing: After a status flag is read as 1 by the CPU, it is cleared by writing
0 to it. When the DTC/DMAC is activated, the flag is cleared automatically. Figure 11.68 shows
the timing for status flag clearing by the CPU, and figure 11.69 shows the timing for status flag
clearing by the DTC/DMAC.
