Where can I find which port pins have been assigned to serial ports A, B, C, and D Tx/Rx function when using RS232 lib?
The Rabbit 5000 uP can use several different port pins function as tx/rx for A, B, C, and D, however, it’s not clear to me after reading the hardware literature what determines pin configuration. It appears from a note on the poster that SPCR might be responsible for this but when I reference SPCR material no mention of serial port is mentioned.
Please help by providing me with the default assignments used by RS232 lib, as well as a reference to where this information is found.
Thanks
