(3) 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.
