TCFV Flag/TCFU Flag Setting Timing:
Figure 12.43 shows the timing for setting of the TCFV flag in TSR by overflow occurrence, and
TCIV interrupt request signal timing. Figure 12.44 shows the timing for setting of the TCFU flag
in TSR by underflow occurrence, and TCIU interrupt request signal timing.
