In event counter mode, external signal inputs to the TRAIO pin are counted (refer to Table 17.4 Event Counter
Mode Specifications).

Count source input
Programmable I/O port or pulse output
The count value can be read by reading registers TRA and TRAPRE.
• When registers TRAPRE and TRA are written while the count is stopped, values

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.
P1_5 or P1_7 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.
