NOTE:
1.
The following registers are disabled in the input capture function: TRDOER1, TRDOER2, TRDOCR,
TRDPOCR0, and TRDPOCR1.
Set the pulse width of the input capture signal applied to the TRDIOji pin to 3 cycles or more of the timer RD
operation clock (refer to Table 14.11 Timer RD Operation Clocks) for no digital filter (the DFj bit in the
TRDDFi register set to 0).
Access registers TRDGRAi to TRDGRDi in 16-bit units. Do not access them in 8-bit units.
