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 10-46 shows the
timing for status flag clearing by the CPU, and figure 10-47 shows the timing for status flag
clearing by the DTC.
Note: * The DTC is not implemented in the H8S/2635 Group.
