(2)
In phase counting mode, TCNT counts up or down according to the phase difference between two
external clocks. There are four modes, according to the count conditions.
(a)
Figure 20.15 shows an example of phase counting mode 1 operation, and table 20.10 summarizes
the TCNT up/down-count conditions.
