R can select between two parents. We deal with it like this: During initialization, check if EXTALR is populated. If so, use it for R. If not, use R_Internal. clk_mux doesn't help here because we don't want to switch parents depending on the clock rate. The clock rate (and source) should stay constant for the watchdog, so I think a setup like this during initialization makes sense.
