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 DMAC is activated, the flag is cleared automatically. Figure 9.42 shows the
timing for status flag clearing by the CPU, and figure 9.43 shows the timing for status flag clearing
by the DMAC.
