In event counter mode, the timer counts overflows/underflows of another timer, or the external pulses.
Table 15.10 lists specifications of event counter mode. Figure 15.28 shows an event counter mode operation.

• External signal applied to the TBiIN pin (i = 0 to 5) (valid edge can be selected
• TBj overflows or underflows (j = i - 1, except j = 2 if i = 0, j = 5 if i = 3)
• Counter decrements
(n + 1) times
The TBiS bit in the TABSR or TBSR register is set to 1 (count starts)
The TBiS bit is set to 0 (count stops)
Count source input
A read from the TBi register returns a counter value.
• A write to the TBi register while the count is stopped:
• A write to the TBi register while counting:
Count starts
by a program)
The value is written to both the reload register and the counter.
The value is written to the reload register (It is transferred to the counter at the
next reload timing).
When the timer underflows, the contents of the reload register are reloaded into
the counter and the count continues.
