In event counter mode, the timer counts how many external signals are applied or how many times
another timer overflows and underflows. The timers A2, A3 and A4 can count externally generated 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 timer A2, A3 and A4). Figure 14.9 shows the TAiMR (i=0 to 4) register in event counter
mode.
