TCFV Flag/TCFU Flag Setting Timing: Figure 11-44 shows the timing for setting of the TCFV
flag in TSR by overflow occurrence, and TCIV interrupt request signal timing.
Figure 11-45 shows the timing for setting of the TCFU flag in TSR by underflow occurrence, and
TCIU interrupt request signal timing.
