GUIDELINE: Provide a method to configure CSEL options.

For debugging purposes, it may be beneficial to allow setting of various CSEL values even if the end product requires just one CSEL setting. If possible, design the board in such a way that the CSEL configuration can be varied even if a single value can be used eventually. This configurability may be useful for debugging and could be done by resistors, jumpers or switches.
