The above applies to the following conditions:
The BFCi and BFDi bits in the TRDMR register are set to 0. (The TRDGRCi and TRDGRDi registers are not used as the buffer register.)
The EBi, ECi and EDi bits in the TRDOER1 register are set to 0. (Enable TRDIOBi, TRDIOCi and TRDIODi pin outputs.)
The TOBi and TOCi bits in the TRDOCR register are set to 0 (inactive level), the TODi bit is set to 1. (active level)
The POLB bit in the TRDPOCRi register is set to 1 (active level “H”), the POLC and POLD bits are set to 0. (active level “L”)
