More than slow_line_nb lines with a phase
error less than the slow_tol will set the
slow status bit, and the pll will work with
the slow time constant.
One or more lines with a phase error more
than slow_tol will reset the slow status bit,
and the pll will work with the fast time
constant.
LSB of slow tol is approx. 200ps.
