Notes:
After Reset
1. When the BFC bit in the TRCMR register is set to 1 (buffer register of TRCGRA register), set the IOC2 bit in the
2. When the BFD bit in the TRCMR register is set to 1 (buffer register of TRCGRB register), set the IOD2 bit in the
3. The IOA3 bit is enabled when the IOA2 bit is set to 1 (input capture function).
