Notes:
After Reset
1. To select 1 (the TRDGRCi register is used as a buffer register of the TRDGRAi register) for this bit by the BFCi
2. To select 1 (the TRDGRDi register is used as a buffer register of the TRDGRBi register) for this bit by the BFDi
3. The IOA3 bit is enabled in the TRDIORA0 register only. Set to the IOA3 bit in TRDIORA1 to 1.
4. The IOA3 bit is enabled when the IOA2 bit is set to 1 (input capture function).
