TCFV Flag/TCFU Flag Setting Timing: Figure 11.41 shows the timing for setting of the TCFV
flag in TSR by overflow occurrence, and the TCIV interrupt request signal timing.
Figure 11.42 shows the timing for setting of the TCFU flag in TSR by underflow occurrence, and
the TCIU interrupt request signal timing.
