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 is activated, the flag is cleared automatically. Figure 10.68 shows the
timing for status flag clearing by the CPU, and Figure 10.69 shows the timing for status flag
clearing by the DTC.
