25 * is the source clk for a root PLL which outputs 1600 and 100 MHz. It is
31 * clock of 100 MHz plus a quotient which gets us as close to the frequency
33 * For the 83.3 MHz example from above this would give us 100 MHz * 5 / 6 =
34 * 83 and 1/3 MHz, which matches exactly what has been measured on actual hw.
80 * 000: 100 * 5 / 6 = 83.3333 MHz
81 * 001: 100 * 1 / 1 = 100.0000 MHz
82 * 010: 100 * 4 / 3 = 133.3333 MHz
83 * 011: 100 * 7 / 6 = 116.6667 MHz
