Write 1 (count starts) to the TSTARTi bit in the TRDSTR register.
Write 0 (count stops) to the TSTARTi bit in the TRDSTR register when
the CSELi bit in the TRDSTR register is set to 1.

Data can be written to the TRDi register.
1 operate synchronously.)
Data can be written to both the TRD0 and TRD1 registers by writing to
the TRDi register.
Either 1 pin or multiple pins of the TRDIOAi, TRDIOBi, TRDIOCi or
TRDIODi pin.
The rising edge, falling edge or both the rising and falling edges
At overflow or input capture
The TRDIOji input is sampled, and when the sampled input level match
3 times, its level is assumed as a determination.
fOCO128 can be selected for input-capture trigger input of the
TRDGRA0 register.
