In event counter mode, the timer counts pulses from an external device or overflows and underflows of
other timers. Timers A2, A3 and A4 can count two-phase external signals. Table 12.2 lists specifications
in event counter mode (when not processing two-phase pulse signal). Table 12.3 lists specifications in
event counter mode (when processing two-phase pulse signal with the timers A2, A3 and A4). Figure
12.8 shows TAiMR register in event counter mode (when not processing two-phase pulse signal). Figure
12.9 shows TA2MR to TA4MR registers in event counter mode (when processing two-phase pulse signal
with the timers A2, A3 and A4).

• External signals input to TAi
• Timer B2 overflows or underflows,
• Increment or decrement can be selected by external signal or program
• When the timer overflows or underflows, it reloads the reload register con-

timer Aj (j=i-1, except j=4 if i=0) overflows or underflows,
timer Ak (k=i+1, except k=0 if i=4) overflows or underflows
tents and continues counting. When operating in free-running mode, the
timer continues counting without reloading.
Value written to TAi register is written to both reload register and counter
Even when the timer overflows or underflows, the reload register content is
not reloaded to it
Whenever the timer underflows or underflows, the output polarity of TAi
pin is inverted . When not counting, the pin outputs a low.
