Two control registers are available to program the output phase offset of the generated clocks. All 16.384 MHz
derived outputs clocks, F16o, F80, F0o, C16o, C8o, C4o and C2o can be collectively shifted up to 125
microseconds with a step size of 60 nS with respect to the input reference by programming the Set Delay Word 1
and Set Delay Word 2 registers.
