In this mode, the timer counts an external signal or an internal timer’s overflow. Timers A0 and A1 can
count a single-phase external signal. Timers A2, A3, and A4 can count a single-phase and a two-phase
external signal. Table 1.14.2 lists timer specifications when counting a single-phase external signal.
Figure 1.14.8 shows the timer Ai mode register in event counter mode.
Table 1.14.3 lists timer specifications when counting a two-phase external signal. Figure 1.14.9 shows
the timer Ai mode register in event counter mode.
