1. By writing to the TRAMR register, the output pulse is set to the level when the pulse output starts.
In event counter mode, external signal inputs to the TRAIO pin are counted (refer to Table 17.4).

The count value can be read out by reading registers TRA and TRAPRE.
• When registers TRAPRE and TRA are written while the count is stopped,
• When registers TRAPRE and TRA are written during count operation, values are

written to the reload register and counter (refer to 17.3.2 Timer Write Control
during Count Operation ).
The active edge of the count source is selected by the TEDGSEL bit in
the TRAIOC register.
Use of the TRAIO pin is selected by bits TRAIOSEL0 to TRAIOSEL1 in the
TRASR register.
Pulses of inverted polarity can be output from the TRAO pin each time the timer
underflows (selectable by the TOENA bit in the TRAIOC register).
Whether enabling or disabling the digital filter and the sampling frequency is
selected by bits TIPF0 and TIPF1 in the TRAIOC register.
The enabled period for the event input to the TRAIO pin is selected by bits
TIOGT0 and TIOGT1 in the TRAIOC register.
