The default incremental closed-loop phase lock offset step size value is 0x03E8 = 1000 (1 ns).
The default phase slew rate limit is 0 (or disabled).
Do not program a timer value of 0. The history accumulation timer default value is 0x007530 = 30,000 (30 sec).

Description
Controls the holdover history. If tuning word history is not available for the
reference that was active just prior to holdover, then
0 (default) = use the free running frequency tuning word register value.
1 = use the last tuning word from the DPLL.
Controls the holdover history initialization. When switching to a new reference
0 (default) = clear the tuning word history.
1 = retain the previous tuning word history.
History mode value from 0 to 7 (default = 0).
