26.4.6 Timing of Interrupt Signal Output on an Overflow
When TCNT overflows (changes from FFh to 00h), an overflow interrupt signal is output if this interrupt request is
enabled.
Figure 26.12 shows the timing of output of the interrupt signal.
For the corresponding interrupt vector number, refer to
section 15, Interrupt Controller (ICUb) and Table 26.6.
