20.5.19 Operating Example
The above applies under the following conditions:
Bits BFCi and BFDi in the TRDMR register are set to 0 (registers TRDGRCi and TRDGRDi are not used as buffer registers).
Bits EBi, ECi and EDi in the TRDOER1 register are set to 0 (enable TRDIOBi, TRDIOCi and TRDIODi pin outputs).
Bits TOBi and TOCi 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”), bits POLC and POLD are set to 0 (active level “L”).
