1. Wait for one or more count source cycles to write after the count starts.
In event counter mode, the timer counts overflows/underflows of another timer, or the external pulse input.
Timers A2, A3, and A4 can count externally generated two-phase signals.
Table 15.4 lists specifications of event counter mode when not handling two-phase pulse signals.
Table 15.5 lists specifications of event counter mode when handling two-phase pulse signals with timers A2,
A3, and A4. Figure 15.15 shows a event counter mode operation when not handling two-phase pulse signals.
Figure 15.16 shows a event counter mode operation when handling two-phase pulse signals with timers A2, A3,
and A4.

Specifications of Event Counter Mode When Not Handling Two-Phase Pulse Signals
• External signal applied to the TAiIN pin (i = 0 to 4) (valid edge is selectable by
• Timer B2 overflows or underflows
• Timer Aj overflows or underflows (j = i - 1, except j = 4 if i = 0)
• Timer Ak overflows or underflows (k = i + 1 except k = 0 if i = 4)
• Count direction (increment or decrement) can be selected by external signal or
• Reload/Free-run type can be selected.
(FFFFh - n + 1): when incrementing
n + 1: when decrementing
The TAiS bit in the TABSR register is set to 1 (count starts)
The TAiS bit is set to 0 (count stops)
Count source input
Pulse output, or input to select the count direction
A read from the TAi register returns a counter value
• A write to the TAi register while the count is stopped:
• A write to the TAi register while counting:
Pulse output function
n: setting value of the TAi register, 0000h to FFFFh
The polarity of the TAiOUT pin is inverted whenever the timer overflows or
underflows. The TAiOUT pin outputs “L” signal while the TAiS bit is 0 (count
stops).

by a program.
Reload function: The contents of the reload register are reloaded into the
counter and the count continues when the timer underflows or overflows.
Free-running function: The counter continues running without reloading when
the timer underflows or overflows.
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).
