20.3.17 Operating Example
The above applies under the following conditions:
Bits CCLR2 to CCLR0 in the TRDCRi register are set to 001b. (the TRDi register set to 0000h by TRDGRAi register input capture).
Bits TCK2 to TCK0 in the TRDCRi register are set to 101b (TRDCLK input for the count source).
Bits CKEG1 to CKEG0 in the TRDCRi register are set to 01b (count at the falling edge for the count source).
Bits IOA2 to IOA0 in the TRDIORAi register are set to 101b (input capture at the falling edge of the TRDIOAi input).
The BFCi bit in the TRDMR register is set to 1 (the TRDGRCi register is used as the buffer register of the TRDGRAi register).
