Default
More than lock_line_nb lines with a phase
error less than the lock_tol will set the lock
status bit, and the pll will work with the lock
time constant.
One or more lines with a phase error more
than lock_tol will reset the lock status bit,
and the pll will work with the slow time
constant.
LSB of lock tol is approx. 200ps.
Phase adjustment.
The maximum phase offset value is equal
to phase_rate[31:21] or 0x40, whichever is
higher.
