If SI/O3 & SI/O4 set at receive only, can SOUTi pin be used as an I/O port?

Latest Updated:09/22/2010

Question:

If SI/O3 and SI/O4 are set for receive only, can the SOUTi pin be used as an I/O port?

Answer:

When SI/O3 and SI/O4 are set for receive only, the SOUTi pin can only be used as an input port (it cannot be used as an output port). When using as an input port, set the SMi2 bit in the SiC register to "1".
