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 9.46 shows the timing
for status flag clearing by the CPU, and figure 9.47 shows the timing for status flag clearing by the
DTC.
