In event counter mode, the timer counts how many external signals are applied or how many times
another timer counter overflows and underflows. The timers A2, A3 and A4 can count externally gener-
ated two-phase signals. Table 14.4 lists specifications in event counter mode (when not handling a two-
phase pulse signal). Table 14.5 lists specifications in event counter mode (when handling a two-phase
pulse signal with the timers A2, A3 and A4). Figure 14.9 shows the TAiMR register (i=0 to 4) in event
counter mode.
