FAQ NO : 106020 Issue Date : Sep.22.10 Functions : Serial Interface Is input or output of the TxDi and RxDi pins determined automatically according to the setting of the serial I/O mode select bit? The TxDi pin is fixed to output mode. The RxDi pin can be set to input mode by setting the port direction register to "0" (input).
