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 is set to 0).
Access the TRDGRAi to TRDGRDi registers in 16-bit units. Do not access them in 8-bit units.
