Latest Updated:03/22/2012

Question:

Is input or output of the TxDi and RxDi pins determined automatically according to the setting of the serial I/O mode select bit?

Answer:

Input or output is not determined automatically. The function select register needs to be set along with the TxDi and RxDi pins.
In addition, the port direction register needs to be set to 0 (input) for the RxDi pin.
