| * options are in one mux and the PLL3 option along with three unused |
| * inputs is in a second mux. There is a third mux with two inputs used |

| * The ldb_di0/1_clk_sel[2] bit controls the 2-port mux. The code below |
| * switches the parent to the bottom mux first and then manipulates the top |
