MMi203: Option links
There are two option links on the MMi203 board that can be read as inputs 13 and 14. You can use these in your program to select alternative operating modes or other end-user options.
On the board they are labeled IN13 and IN14. The jumpers go in the direction illustrated at IN13.
Inputs 13 and 14 are also used on the SPice connector. That means the option jumper function may not be available if there is a SPice board present. In that case you must remove the jumpers before installing the SPice board.
