IOA3: Bit in TRCIOR0 register
Notes:
1. The BFC bit in the TRCMR register is set to 1 (TRCGRC register functions as the buffer register for the TRCGRA register)
2. The BFD bit in the TRCMR register is set to 1 (TRCGRD register functions as the buffer register for the TRCGRB register)
3. The trigger input of the TRCGRA register can select the TRCIOA pin input or fOCO128 signal.
