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 1.40
lists timer specifications when counting a single-phase external signal. Table 1.41 lists timer specifications when
counting a two-phase external signal. Figure 1.82 shows the Timer Ai mode register in event counter mode (excluding
two-phase pulse signal processing). Figure 1.83 shows the Timer Ai mode register in event counter mode when using
two-phase pulse signal processing.
