These three bits will adjust timing of FBOUTT signal either positive
or negative delay up to +800ps or –600ps with 200ps per step.
(see Table 1)
These four bits will program the propagation delay from CLK_INT
to the input of PLL within the range between 0ps and 2.5ns with
170ps step size. (see Table 2)
