Data can be written to the TRDi register.
Data can be written to both the TRD0 and TRD1 registers by writing to
the TRDi register.
Either 1 pin or multiple pins among TRDIOAi, TRDIOBi, TRDIOCi, or
TRDIODi.
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 as 3 times, the level is determined.
fOCO128 can be selected for input-capture trigger input of the
TRDGRA0 register.
