The above applies under the following conditions:
• The CCLR bit in the TRCCR1 register is set to 1 (Clear TRC counter by input capture).
• Bits TCK2 to TCK0 in the TRCCR1 register are set to 101b (the count source is TRCCLK input).
• Bits IOA2 to IOA0 in the TRCIORA register are set to 101b (input capture at the falling edge of the TRCIOA input).
• The BFC bit in the TRCMR register is set to 1 (the TRCGRC register functions as the buffer register for the TRCGRA register).
